Focus on Competition - 2003/03

2005 Rules Change Cycle
Basic Rules Change Proposals
The following are the Basic Rules Change Proposals that have been submitted for
consideration in the 2005 Rules Change Cycle. These proposals have been
reviewed by each Contest Board chairperson and/or the Executive Council
(depending on jurisdiction).
The proposals are now being published to allow the AMA membership an
opportunity to comment to those voting before action takes place. If any of these
proposals are of interest to you, you are encouraged to contact the appropriate
Contest Board representative for the event and your AMA district. If the
proposal is under Executive Council jurisdiction, please contact your district
vice president to make your comments.
All proposals will be voted on in February. Proposals that pass this initial vote
will continue to be considered during subsequent voting. Proposals failing the initial
vote will no longer be considered. Please contact the Competition Department if
you have any questions or need complete copies of proposals not reproduced in
their entirety here.

Change to:
2. General. A Free Flight electric Power model airplane is powered by a
motor that receives as its sole source of power, energy from rechargeable
batteries rated at 1.5 volts per cell or less, self-contained in the model.
2.1 The following events have been established according to the
number of rechargeable battery cells used:
160 Class A—Six (6) cells or less
161 Class B—More than six (6) cells
Submitted by: Francis B. Hodson, AMA 1688
OFF-05-3, page 18, Free Flight Electric Power for events 160 & 161.
Change to:
1. Motor Run/Flight Maximum. The length of the motor run after the
model has been released for flight shall be twenty (20) seconds, excluding
flyoff flights. The maximum recorded duration for each flight shall be
two (2) minutes, including qualified flyoff flights.
3.1 All models shall be hand launched. Launching shall be as
specified for hand launch of land plane models, FF General.
Change to:
6. Number of Flights. Each contestant shall be allowed a total of six (6)
attempts to make three (3) official flights. All official and unofficial
flights are described above are attempts.
6.1 If the three (3) official flights total the maximum allowed, then a
series of flyoff flights may be taken. Flyoff flights may continue until the
contestant’s model fails to reach the flight maximum. Only one (1)
attempt is permitted for each flyoff flight. Flyoff motor runs are as
follows:

WE HAVE REACHED the first critical
stage in the 2005 Rules Change Cycle. All
basic rules change proposals have been
received, reviewed, and are now being
published in this copy of Model Aviation so
that the membership may make comments
on them.
This is the critical part. If you fly in
competition, you should read every
proposal that has anything to do with the
events you fly. The critical part is that you
should make comments regarding the
proposal to the proper Contest Board
representative for that discipline and your
district. The Contest Board members are in
place to represent their constituents’ views
on competition matters. If they do not hear
from the membership, it becomes difficult
for them to properly represent these views.
So do your part; let them know what you
think!
In February of 2003 I will be sending the
initial ballot for these proposals to all of the
Contest Boards. Those proposals that fail
the initial ballot will no longer be
considered. Those that pass will continue on
through the interim and final votes (more on
that part of the cycle in a future column).
One last thing for this column (short due
to the many pages needed to publish the
basic proposals): I have another Urgent
Rules Change Proposal to publish. Due to
the nature of this proposal it was assigned to
the Executive Council for consideration.
Proposals are assigned to the Executive
Council when the issue is perhaps
contentious due to it affecting two or more
Contest Boards or when the issue is clearly
an item that falls under EC jurisdiction.
Approximately four weeks after this
publication I will be taking a ratification
vote. If passed, the proposal will go into
effect January 1.
Urgent Rules Change Proposal
Wording for change: Proposal seeks to
move events 501 (Outdoor Peanut Scale),
503 (Outdoor Flying Rubber Scale) and
504 (Outdoor Gas Power Scale) from
Scale Contest Board jurisdiction to the
Free Flight Contest Board jurisdiction. The
events would also move to the Free Flight
category in the Competition Regulations.
Logic behind proposed change: The Free
Flight Outdoor Scale events are all but
dead, while events such as Flying Aces
Club events continue to grow in
popularity. In 2002 the Nats was one of the
only events to offer AMA Free Flight
Scale events; other events offered FAC
Scale. The Scale Contest Board is
composed of people who are experts in
controlled flight but have little experience
with the issues facing the Free Flight
community.

CLS-05-6: Page 41, section “ESTABLISHMENT OF LINE SIZES AND
PULL TESTS IN CL SPEED”, under paragraph “Implementation”.
IMPLEMENTATION: It is the responsibility of the Control Line Speed
Contest Board Chairman to monitor and maintain the line sizes and pull tests
as described above. In the event a new record is established which
necessitates an increase in line size, pull test, or both, any changes will be
published concurrently with announcement of new record.
In the case of a record established on a newly increased line size, whereby the
previous pull test standard exceeds the need of the new record, the CLSCB
Chairman will establish a new appropriate pull test standard. For all classes
that have 48G and higher pull tests, the new standard will be no less than 48G.
Changes will become effectively immediately upon publication in Model
Aviation magazine. Changes are to be automatic, with no action required by
the control line speed contest board or the AMA Executive Council.

the upwind and downwind marker poles. When approximately over this line
the model turns either 90 degrees or 270 degrees for a downwind trim pass.
When approximately even with the downwind marker the model initiates a
180-degree turn, reversal or other turn-around maneuver of pilot’s choice.

1. PREFACE
The purpose of this Scale Aerobatics Flying and Judging Guide is to provide
an accurate description of each type of maneuver used in competition and to
provide a reference for use in developing a uniformly high standard of
judging in all AMA sanctioned contests. Study of this guide by the
competitor will help him or her learn exactly what is expected, while study
by the judges will help them decide precisely how well the competitor meets
these expectations.
Flying and judging are very similar in nature; this is why contestant judging
is generally promoted. Nevertheless, there are some key differences between
judges and pilots, mostly related to Mental Attitude and Technical
Knowledge. Reference to any gender in this document shall include both
male and female.

Scale Aerobatics maneuvers also use the standard K-factors defined by the
FAI, but with two exceptions:
1) The FAI K-Factors for Rolling circle maneuvers (Family 2.3 to 2.20) must
be doubled (i.e.: A FAI K-factor of 13 should become 26).
2) The FAI K-Factor for Tailslide maneuvers (Family 6) must be multiplied
by one and half (1.5) (i.e.: a FAI K-Factor of 16 should become 24). When
the original FAI K-Factor is an odd number, the result of the multiplication
used should be reduced to the lower whole number (i.e.: a FAI K-Factor of
15 should become 22, or 15+7.5=22.5, reduced to the lower number=22).

3. RULES
Scale Aerobatics has several rules that differ from either Full Scale
Aerobatics (IAC) or AMA RC Aerobatics (AMA Pattern). Because the
judging pool used in Scale Aerobatics contests sometimes comes from both
or either of those two groups, it is useful to go through the major differences:
Submitted by: Thomas Wheeler, AMA 405590
RCA-05-37: Page 92, change as follows:
4. RCA-05-37: Positioning
Scale Aerobatics requires all scored maneuvers to be flown in front of the
judges, in an area called the “box”. Competitors should perform their
sequence within the aerobatic box balance about the center of the x-axis and
at an optimal distance from the judges. Judges will give the position grade
according to the total impression of the balanced use of the aerobatic box and
the overall presentation of the sequence. It is not required, however, to use all
the available airspace vertically or on the x or y-axis. As a judge, what is
important is that you apply the same presentation criteria in consistent
manner to every pilot flying the program. The range of possible scores is
from 10 to 0 in .5 increments.
If the sun is positioned such that it hampers positioning and judging of any
maneuvers, the contestant may request the judges to allow an offset of certain
maneuvers. This agreement shall take place prior to the start of the flight.
Also, flying the figures in the front or the back of the box while on the X-axis
is not a criterion for judging. Before entering the box, the pilot or caller
should announce to the judges the direction of flight (Left-to-Right or Rightto-
Left). This is completely the pilot’s option and independent of the wind
direction. Once this announcement is made, the relationship and positioning
between maneuvers is defined by the Aresti sequence drawing.
Category Positioning coefficients are as follows:
Basic 5K
Sportsman 10K
Intermediate 15K
Advanced 20K
Unlimited 25K

RCA-05-38: Page 92
4.1 Scale Aerobatic Box
Two (2) horizontal lines, 90 degrees to each side of the centerline. The total
length of the box shall be 2000 feet (610 meters) along a line parallel to the
flight line. The rear boundary of the box shall be a line parallel to the flight
line and 1000 feet (305 meters) from the competitors position.
Whenever the “complete aircraft” is observed to fly past any boundary, an
infringement penalty will be noted by the maneuver score being circled by
the judge. It should be noted that the judges could disagree on box
infringements (i.e. one judge circles the maneuver and the other doesn’t). The
penalty will be assessed when the scores are tabulated and vary by the class
flown:
i. Basic = two (2) points per infringement
ii. Sportsman = four (4) points per infringement
iii. Intermediate = six (6) points per infringement
iv. Advanced = eight (8) points per infringement
v. Unlimited = ten (10) points per infringement
Because the judges are located behind the pilot, the only box infringements
generally noted are the one that can easily be assessed using the 90 degree
markers reference on the ground. Although judging the side and back
infringements are more difficult due to the lack of references, judges should
still take them into account if the aircraft clearly goes past these boundaries.
In case of uncertainty, always give the competitor the benefit of the doubt.

RCA-05-43: New Event. Indoor RC Aerobatics.
It is the intention to provide a safe aerobatic event for electric powered
models that will be flown indoors. Wherever possible, the rules will be the
same as outdoor radio control pattern. Rather than reproduce the entire set
of pattern rules, the exceptions will be noted.
4. Model aircraft requirements.
4.1 Power. Models shall be powered by battery powered electric
motors. The maximum battery voltage shall be 9.6 volts (manufacturers
ratings). No limit is placed on the number of motors, but the maximum
power delivered to the motor(s) shall be 30 watts. In cases where there is a
question, the contestant may be required to sign an affidavit stating that his
entry conforms to this rule.
4.2 Weight and size. No model shall weigh more than 7 ounces ready to
fly.
1.5 Change radius of spinner tip to 2 millimeters.
7. Pattern event classes.
The indoor pattern event shall be divided into two classes. The first, (class
I) shall be open to any model design that meets the weight and power
criteria. The second (class II) will be limited to models which clearly
resemble an aircraft used in aerobatic competition. This includes outdoor
pattern event models as well as full scale aircraft. Both classes will fly the
same maneuver pattern.
8. Contestant classification. This system will not be used in indoor
aerobatics. Delete sections 8.-8.3.
10. Official flight. Change time limit to two (2) minutes.
11. Time limits. Change time to (2) minutes.
14. The CD will determine the boundary limits for the “box” based on site
conditions, as well as the distance from the judges for the flight path of
maneuvers.

As such, it is not a suitable event for the use of engines that some with
tuned mufflers or otherwise are capable of turning a stock 9 x 6 APC
propeller at over 16, 500 rpm on the ground.
Reword paragraph 6:
“Sport Quickie is intended as an entry-level event for pilots who are
new to racing. Sample engines are tested via committee and a list of
permissible engines is published and updated as necessary, annually.
Criteria include purchase price and power output in both the normal
takeoff RPM range and the presumed in-air (“unloaded”) RPM range.
Any engine with a tuned muffler is strictly prohibited. The cost of the
engine must be below $120 (street price). If engines more powerful than
this are to be used at a contest, the contest should be sanctioned as
Quickie 500 (Event No. 428), not sport Quickie.”
Add paragraph 7:
“Prior approval of engines”.
a). Procedure: All engines, past and future inclusive, shall not be
entered into competition until a five-member sub-committee of the RC
Racing Contest Board has approved the engine by an affirmative vote of
at least three members thereof. Such approval may be given orally, but
shall be recorded for future reference. An engine shall be considered
eligible for competition if it meets all requirements of section 16.3.2
and, in addition, does not hinder the state of this entry level event as
determined by the aforementioned five-member committee. The
committee is appointed by the Racing Contest Board Chairman and will
not include any member with a vested interest in the sale of
manufacturing of an engine for this event. In addition any engine can be
removed from the list by an affirmative vote of at least three members
thereof.
Under section 16.3.3. Special Provisions, sub-section b. Rule Variations
Permitted: Remove item #1: Approval engine list: Sample engines are
tested and a list of permissible engines is published annually. Criteria
include purchase price and power output in both the normal takeoff rpm

1.1 No object, device in its fully extended position, or part thereof can
protrude ahead of the nose of the aircraft.
1.2 Ahead of the leading edge of the wing, no part of an object or device in
its fully extended position can protrude more than one inch below the bottom
of the fuselage. If the fuselage bottom is curved, the length of the protrusion
or part thereof will be measured along the perpendicular to a tangent to the
fuselage at the point where the measurement is to be made. 1.3 From the
leading edge of the wing to the rearmost part of the fuselage, no part of an
object or device in its fully extended position can protrude more than three
inches below the bottom of the wing or an extension thereof. Measurements
will be made along a perpendicular to the bottom of the wing at the point in
question. In the event that an object/device is located behind the trailing edge
of the wing, the extension of the bottom of the sing will be determined by
placing a straight edge so that it is in contact with at least two points along
the bottom of the wing and measuring along a perpendicular to the side of the
straight edge that is in contact with the bottom of the wing. Flaps must be
fully retracted when measurements are made.
1.4 The forward facing edge of an object or device in its fully extended
position must have a radius of a t least 0.25 inch in the vertical plane.
1.5 All objects or devices in their fully extended position must lay in a single
plane that is perpendicular to the bottom surface of the wing and congruent
with the centerline of the fuselage.
1.6 The above rules do not apply to those classes that specifically prohibit the
use of devices whose intent it is to produce a rapid deceleration when
landing.

flying segment.
1. ELIGIBILITY. The contest is open to modeler-built or factory built
CL Scale models. The event rules are identical to event #509, Control Line
Sport Scale except for static judging. General rule 4 (builder — flier) will
not apply in this event. With advance notice, the event may be conducted
in different classes based on skill or age level, i.e., Open, Entry, Junior,
Senior, etc.
2. STATIC JUDGING. The static scale outline score will be a graduated
zero (0) to five (5) points to contestants who show proof that a full size
aircraft or this type did/does exist. An additional score of a graduated zero (0)
to (5) points will be awarded if proof is shown as to replicating a
color/markings scheme of the original full size aircraft. A single sheet (3-
view drawing, photo, profile, painting, plastic kit box, etc.) is sufficient.
Contestant prepared drawings of a photo of the model itself is not acceptable.
If no proof of existence or color/markings is shown, no static points will be
awarded. However, it will be up to the contest director and/or event director
to determine if the scale model is indeed a replica of a full size aircraft of r
contest
eligibility.
3. FLYING. All rules as per CL Sport Scale (event #509).
4. SCORING. The official score shall be the total of static points (10
maximum) and the single best flight score (100 maximum) for a total of 110
points.

RC Electric
ECL-05-1 page 186 Adds new event: Elexaco
Summary of Elexaco Competition Rules: (Old Timer or Open) The
investment flying electric using a 400 motor is nominal as an existing radio
with at least 3 channels is all that is needed. What makes it real interesting is
that the performance of a 7 cell battery pak with a direct 400 motor system is
outstanding. Using alkaline battery cells in the Tx makes the model always
available for flight when stored in the trunk of your car. Due to the small size
it is stored assembled. In traveling where a field is sited (A football field will
do) simply stop, charge the flight battery for motor and RX power by BEC
and fly as the alkalines for the TX are always ready. Now to add interest a
simple endurance competitive event was designed that can be decided at the
flying field. All that is required is a stop watch. To establish equity the
Elexaco event is offered making it easy as it defines specifically the
hardware required. It is designed as an electric version of the ever popular
1⁄2A Glo-Powered Texaco event and can be restricted to old-timer if desired
by option.
Elexaco Event Rules
1. Any model with an aspect wing ratio of less than 7 qualifies (wingspan
divided by center chord).

2. Any rated 400 Electric ferrite motor (not brushless or cobalt and not geared)
qualifies.
3. A 7 cell 250 to 350 MAH power pak must be used.
4. Any motor shut off device is acceptable.
Flight Rules
Timed from either take-off or hand launch, motor is allowed to fun for 2 minutes
and shut off by radio—if motor is shut off prior to 2 minutes it is not to be turned
back on—if turned back on score is 0. Flight is continued and timed toward max
flight time of 15 minutes to land at designated field. Score 1 point per second
(max 900 points). Exceeding max results in penalty of 1 point per second.

WE HAVE REACHED the first critical
stage in the 2005 Rules Change Cycle. All
basic rules change proposals have been
received, reviewed, and are now being
published in this copy of Model Aviation so
that the membership may make comments
on them.
This is the critical part. If you fly in
competition, you should read every
proposal that has anything to do with the
events you fly. The critical part is that you
should make comments regarding the
proposal to the proper Contest Board
representative for that discipline and your
district. The Contest Board members are in
place to represent their constituents’ views
on competition matters. If they do not hear
from the membership, it becomes difficult
for them to properly represent these views.
So do your part; let them know what you
think!
In February of 2003 I will be sending the
initial ballot for these proposals to all of the
Contest Boards. Those proposals that fail
the initial ballot will no longer be
considered. Those that pass will continue on
through the interim and final votes (more on
that part of the cycle in a future column).
One last thing for this column (short due
to the many pages needed to publish the
basic proposals): I have another Urgent
Rules Change Proposal to publish. Due to
the nature of this proposal it was assigned to
the Executive Council for consideration.
Proposals are assigned to the Executive
Council when the issue is perhaps
contentious due to it affecting two or more
Contest Boards or when the issue is clearly
an item that falls under EC jurisdiction.
Approximately four weeks after this
publication I will be taking a ratification
vote. If passed, the proposal will go into
effect January 1.
Urgent Rules Change Proposal
Wording for change: Proposal seeks to
move events 501 (Outdoor Peanut Scale),
503 (Outdoor Flying Rubber Scale) and
504 (Outdoor Gas Power Scale) from
Scale Contest Board jurisdiction to the
Free Flight Contest Board jurisdiction. The
events would also move to the Free Flight
category in the Competition Regulations.
Logic behind proposed change: The Free
Flight Outdoor Scale events are all but
dead, while events such as Flying Aces
Club events continue to grow in
popularity. In 2002 the Nats was one of the
only events to offer AMA Free Flight
Scale events; other events offered FAC
Scale. The Scale Contest Board is
composed of people who are experts in
controlled flight but have little experience
with the issues facing the Free Flight
community.

as described above. In the event a new record is established which
necessitates an increase in line size, pull test, or both, any changes will be
published concurrently with announcement of new record.
In the case of a record established on a newly increased line size, whereby the
previous pull test standard exceeds the need of the new record, the CLSCB
Chairman will establish a new appropriate pull test standard. For all classes
that have 48G and higher pull tests, the new standard will be no less than 48G.
Changes will become effectively immediately upon publication in Model

the following to Radio Control Aerobatics, No. 14 Flight pattern and
maneuvering area. Calling of box entry must be done so there is a minimum
of a 15 meter straight line before the first maneuver. Judging of the maneuver
will begin then. (As the lines into and out of maneuvers are part of the
maneuver and are always judged). Calling of exiting the box must be done
after a minimum of a 15 meter straight line after the maneuver. Judging will
cease at that point.

Fly a downwind leg, and then turn 180 degrees into the wind for a final
approach to the runway touching down in the landing zone. The landing is
complete when the model has either rolled 10 meters or comes to rest.
Landing Zone: The landing zone shall be marked by lines placed
perpendicular across the runway and spaced 100 meters apart. The width of
the landing zone shall normally be the width of the runway but in no case
shall exceed 30 meters.
Downgrades:
1. Model does not follow landing sequence zero (0) points.
2. Any landing gear leg retracts or collapses on landing, zero (0) points.
3. Model ends up on its back, zero (0) points.
4. Model passes behind the judges’ line (“flight line”), zero (0) points.
5. Model land outside of the landing zone, zero (0) points.
6. Only two scores a 10 or a 0 may be awarded for the landing sequence.
Take-off Sequence: The model is placed on the runway, takes off from
within the landing zone, then turns 90 degrees toward the line defined by
the upwind and downwind marker poles. When approximately over this line
the model turns either 90 degrees or 270 degrees for a downwind trim pass.
When approximately even with the downwind marker the model initiates a
180-degree turn, reversal or other turn-around maneuver of pilot’s choice.
Downgrades:

1. PREFACE
The purpose of this Scale Aerobatics Flying and Judging Guide is to provide
an accurate description of each type of maneuver used in competition and to
provide a reference for use in developing a uniformly high standard of
judging in all AMA sanctioned contests. Study of this guide by the
competitor will help him or her learn exactly what is expected, while study
by the judges will help them decide precisely how well the competitor meets
these expectations.
Flying and judging are very similar in nature; this is why contestant judging
is generally promoted. Nevertheless, there are some key differences between
judges and pilots, mostly related to Mental Attitude and Technical
Knowledge. Reference to any gender in this document shall include both
male and female.

Scale Aerobatics maneuvers also use the standard K-factors defined by the
FAI, but with two exceptions:
1) The FAI K-Factors for Rolling circle maneuvers (Family 2.3 to 2.20) must
be doubled (i.e.: A FAI K-factor of 13 should become 26).
2) The FAI K-Factor for Tailslide maneuvers (Family 6) must be multiplied
by one and half (1.5) (i.e.: a FAI K-Factor of 16 should become 24). When
the original FAI K-Factor is an odd number, the result of the multiplication
used should be reduced to the lower whole number (i.e.: a FAI K-Factor of
15 should become 22, or 15+7.5=22.5, reduced to the lower number=22).

3. RULES
Scale Aerobatics has several rules that differ from either Full Scale
Aerobatics (IAC) or AMA RC Aerobatics (AMA Pattern). Because the
judging pool used in Scale Aerobatics contests sometimes comes from both
or either of those two groups, it is useful to go through the major differences:
Submitted by: Thomas Wheeler, AMA 405590
RCA-05-37: Page 92, change as follows:
4. RCA-05-37: Positioning
Scale Aerobatics requires all scored maneuvers to be flown in front of the
judges, in an area called the “box”. Competitors should perform their
sequence within the aerobatic box balance about the center of the x-axis and
at an optimal distance from the judges. Judges will give the position grade
according to the total impression of the balanced use of the aerobatic box and
the overall presentation of the sequence. It is not required, however, to use all
the available airspace vertically or on the x or y-axis. As a judge, what is
important is that you apply the same presentation criteria in consistent
manner to every pilot flying the program. The range of possible scores is
from 10 to 0 in .5 increments.
If the sun is positioned such that it hampers positioning and judging of any
maneuvers, the contestant may request the judges to allow an offset of certain
maneuvers. This agreement shall take place prior to the start of the flight.
Also, flying the figures in the front or the back of the box while on the X-axis
is not a criterion for judging. Before entering the box, the pilot or caller
should announce to the judges the direction of flight (Left-to-Right or Rightto-
Left). This is completely the pilot’s option and independent of the wind
direction. Once this announcement is made, the relationship and positioning
between maneuvers is defined by the Aresti sequence drawing.
Category Positioning coefficients are as follows:
Basic 5K
Sportsman 10K
Intermediate 15K
Advanced 20K
Unlimited 25K

RCA-05-38: Page 92
4.1 Scale Aerobatic Box
Two (2) horizontal lines, 90 degrees to each side of the centerline. The total
length of the box shall be 2000 feet (610 meters) along a line parallel to the
flight line. The rear boundary of the box shall be a line parallel to the flight
line and 1000 feet (305 meters) from the competitors position.
Whenever the “complete aircraft” is observed to fly past any boundary, an
infringement penalty will be noted by the maneuver score being circled by
the judge. It should be noted that the judges could disagree on box
infringements (i.e. one judge circles the maneuver and the other doesn’t). The
penalty will be assessed when the scores are tabulated and vary by the class
flown:
i. Basic = two (2) points per infringement
ii. Sportsman = four (4) points per infringement
iii. Intermediate = six (6) points per infringement
iv. Advanced = eight (8) points per infringement
v. Unlimited = ten (10) points per infringement
Because the judges are located behind the pilot, the only box infringements
generally noted are the one that can easily be assessed using the 90 degree
markers reference on the ground. Although judging the side and back
infringements are more difficult due to the lack of references, judges should
still take them into account if the aircraft clearly goes past these boundaries.
In case of uncertainty, always give the competitor the benefit of the doubt.

It is the intention to provide a safe aerobatic event for electric powered
models that will be flown indoors. Wherever possible, the rules will be the
same as outdoor radio control pattern. Rather than reproduce the entire set
of pattern rules, the exceptions will be noted.
4. Model aircraft requirements.
4.1 Power. Models shall be powered by battery powered electric
motors. The maximum battery voltage shall be 9.6 volts (manufacturers
ratings). No limit is placed on the number of motors, but the maximum
power delivered to the motor(s) shall be 30 watts. In cases where there is a
question, the contestant may be required to sign an affidavit stating that his
entry conforms to this rule.
4.2 Weight and size. No model shall weigh more than 7 ounces ready to
fly.
1.5 Change radius of spinner tip to 2 millimeters.
7. Pattern event classes.
The indoor pattern event shall be divided into two classes. The first, (class
I) shall be open to any model design that meets the weight and power
criteria. The second (class II) will be limited to models which clearly
resemble an aircraft used in aerobatic competition. This includes outdoor
pattern event models as well as full scale aircraft. Both classes will fly the
same maneuver pattern.
8. Contestant classification. This system will not be used in indoor
aerobatics. Delete sections 8.-8.3.
10. Official flight. Change time limit to two (2) minutes.
11. Time limits. Change time to (2) minutes.

As such, it is not a suitable event for the use of engines that some with
tuned mufflers or otherwise are capable of turning a stock 9 x 6 APC
propeller at over 16, 500 rpm on the ground.
Reword paragraph 6:
“Sport Quickie is intended as an entry-level event for pilots who are
new to racing. Sample engines are tested via committee and a list of
permissible engines is published and updated as necessary, annually.
Criteria include purchase price and power output in both the normal
takeoff RPM range and the presumed in-air (“unloaded”) RPM range.
Any engine with a tuned muffler is strictly prohibited. The cost of the
engine must be below $120 (street price). If engines more powerful than
this are to be used at a contest, the contest should be sanctioned as
Quickie 500 (Event No. 428), not sport Quickie.”
Add paragraph 7:
“Prior approval of engines”.
a). Procedure: All engines, past and future inclusive, shall not be
entered into competition until a five-member sub-committee of the RC
Racing Contest Board has approved the engine by an affirmative vote of
at least three members thereof. Such approval may be given orally, but
shall be recorded for future reference. An engine shall be considered
eligible for competition if it meets all requirements of section 16.3.2
and, in addition, does not hinder the state of this entry level event as
determined by the aforementioned five-member committee. The
committee is appointed by the Racing Contest Board Chairman and will
not include any member with a vested interest in the sale of
manufacturing of an engine for this event. In addition any engine can be
removed from the list by an affirmative vote of at least three members
thereof.

1.2 Ahead of the leading edge of the wing, no part of an object or device in
its fully extended position can protrude more than one inch below the bottom
of the fuselage. If the fuselage bottom is curved, the length of the protrusion
or part thereof will be measured along the perpendicular to a tangent to the
fuselage at the point where the measurement is to be made. 1.3 From the
leading edge of the wing to the rearmost part of the fuselage, no part of an
object or device in its fully extended position can protrude more than three
inches below the bottom of the wing or an extension thereof. Measurements
will be made along a perpendicular to the bottom of the wing at the point in
question. In the event that an object/device is located behind the trailing edge
of the wing, the extension of the bottom of the sing will be determined by
placing a straight edge so that it is in contact with at least two points along
the bottom of the wing and measuring along a perpendicular to the side of the
straight edge that is in contact with the bottom of the wing. Flaps must be
fully retracted when measurements are made.
1.4 The forward facing edge of an object or device in its fully extended
position must have a radius of a t least 0.25 inch in the vertical plane.
1.5 All objects or devices in their fully extended position must lay in a single

SCA-05-2, Add new event: Control Line Fun Scale
The intent of Fun Scale is to provide a CL Scale event, which is, and is to
remain, simple in concept. It minimizes the static judging and emphasizes the
flying segment.
1. ELIGIBILITY. The contest is open to modeler-built or factory built
CL Scale models. The event rules are identical to event #509, Control Line
Sport Scale except for static judging. General rule 4 (builder — flier) will
not apply in this event. With advance notice, the event may be conducted
in different classes based on skill or age level, i.e., Open, Entry, Junior,
Senior, etc.
2. STATIC JUDGING. The static scale outline score will be a graduated
zero (0) to five (5) points to contestants who show proof that a full size
aircraft or this type did/does exist. An additional score of a graduated zero (0)
to (5) points will be awarded if proof is shown as to replicating a
color/markings scheme of the original full size aircraft. A single sheet (3-
view drawing, photo, profile, painting, plastic kit box, etc.) is sufficient.
Contestant prepared drawings of a photo of the model itself is not acceptable.
If no proof of existence or color/markings is shown, no static points will be
awarded. However, it will be up to the contest director and/or event director
to determine if the scale model is indeed a replica of a full size aircraft of r
contest
eligibility.
3. FLYING. All rules as per CL Sport Scale (event #509).
4. SCORING. The official score shall be the total of static points (10
maximum) and the single best flight score (100 maximum) for a total of 110
points.

Event, revises rules to specifically allow for indoor flying of RC Scale
models in these events.
Revise current section 2. Safety Requirements
Leave items 2.1, 2.2, 2.3, 2.4, 2.5 as is.
Re-number 2.8 to 2.6.
Add new section 3. Outdoor Events
3.1. There are no restrictions as to types of power plants that may be used in
R/C Sport Scale models that are flown outdoors. Reciprocating internal
combustion engines (including 2-stroke, 4-stroke, glow, gas, CO2,
compressed air), electric motors, and turbojet engines are allowed.
3.2. (same as old section “2.7. Turbojet engines “
3.3. With the exception of electric motors, the engine(s) must be equipped
with an effective muffler or silencer to limit noise output. A tuned pipe is
considered a muffler.
3.4. R/C Sport Scale models that are flown outdoors shall weigh no more
than 55 pounds, ready for flight, including fuel.
Add a new section 4. Indoor Events
4.1. R/C Sport Scale models that are flown indoors must be powered with
electric, CO2, orcompressed air motor(s). No other type of power plant is
permissible for indoor flying.
4.2. R/C sport Scale models that are flown indoors shall weigh no more than
12 ounces ready for flight, including fuel or batteries.
4.3. Maximum wing loading of the model, ready for flight, shall not exceed 6
ounces per square foot.
4.4. Due to wide variations in the size and shape of indoor flying sites, the
Contest Director has authority to adjust sections 4.2. and 4.3. as needed to fit
the contest flying site and local conditions. In all cases, any deviation from
these rulebook specifications must be noted in all pre-contest announcements
and literature well in advance of the event.
4.5. Because of the size restrictions that indoor flying naturally imposes on
the flight of a model, the Contest Director has authority to adjust any of the
maneuver descriptions in the “Radio Control Scale Flight Judging Guide” to
03sig6.QXD 12.20.02 11:17 am Page 182

fit the size of his facility. For example, the Judging Guides says that the Fly-
Past should be flown between 10 — 20 feet altitude for at least 5 seconds. At
many indoor flying facilities that would be impossible. In all cases, any
deviation from the Judging Guide maneuver descriptions must be noted in all
pre-contest announcements and literature well in advance of the event.
Revise current section 3. Model Requirements
Delete third paragraph; “With the exception of electric motors, the engine
must be equipped with an effective muffler “
Re-number current sections 3 through 11 as sections 5 through 13
respectively.

RC Electric
ECL-05-1 page 186 Adds new event: Elexaco
Summary of Elexaco Competition Rules: (Old Timer or Open) The
investment flying electric using a 400 motor is nominal as an existing radio
with at least 3 channels is all that is needed. What makes it real interesting is
that the performance of a 7 cell battery pak with a direct 400 motor system is
outstanding. Using alkaline battery cells in the Tx makes the model always
available for flight when stored in the trunk of your car. Due to the small size
it is stored assembled. In traveling where a field is sited (A football field will
do) simply stop, charge the flight battery for motor and RX power by BEC
and fly as the alkalines for the TX are always ready. Now to add interest a
simple endurance competitive event was designed that can be decided at the
flying field. All that is required is a stop watch. To establish equity the
Elexaco event is offered making it easy as it defines specifically the
hardware required. It is designed as an electric version of the ever popular
1⁄2A Glo-Powered Texaco event and can be restricted to old-timer if desired
by option.
Elexaco Event Rules
1. Any model with an aspect wing ratio of less than 7 qualifies (wingspan
divided by center chord).
03sig6.QXD 12.20.02 11:17 am Page 183
184 MODEL AVIATION
2. Any rated 400 Electric ferrite motor (not brushless or cobalt and not geared)
qualifies.
3. A 7 cell 250 to 350 MAH power pak must be used.
4. Any motor shut off device is acceptable.
Flight Rules
Timed from either take-off or hand launch, motor is allowed to fun for 2 minutes
and shut off by radio—if motor is shut off prior to 2 minutes it is not to be turned
back on—if turned back on score is 0. Flight is continued and timed toward max
flight time of 15 minutes to land at designated field. Score 1 point per second
(max 900 points). Exceeding max results in penalty of 1 point per second.

WE HAVE REACHED the first critical
stage in the 2005 Rules Change Cycle. All
basic rules change proposals have been
received, reviewed, and are now being
published in this copy of Model Aviation so
that the membership may make comments
on them.
This is the critical part. If you fly in
competition, you should read every
proposal that has anything to do with the
events you fly. The critical part is that you
should make comments regarding the
proposal to the proper Contest Board
representative for that discipline and your
district. The Contest Board members are in
place to represent their constituents’ views
on competition matters. If they do not hear
from the membership, it becomes difficult
for them to properly represent these views.
So do your part; let them know what you
think!
In February of 2003 I will be sending the
initial ballot for these proposals to all of the
Contest Boards. Those proposals that fail
the initial ballot will no longer be
considered. Those that pass will continue on
through the interim and final votes (more on
that part of the cycle in a future column).
One last thing for this column (short due
to the many pages needed to publish the
basic proposals): I have another Urgent
Rules Change Proposal to publish. Due to
the nature of this proposal it was assigned to
the Executive Council for consideration.
Proposals are assigned to the Executive
Council when the issue is perhaps
contentious due to it affecting two or more
Contest Boards or when the issue is clearly
an item that falls under EC jurisdiction.
Approximately four weeks after this
publication I will be taking a ratification
vote. If passed, the proposal will go into
effect January 1.
Urgent Rules Change Proposal
Wording for change: Proposal seeks to
move events 501 (Outdoor Peanut Scale),
503 (Outdoor Flying Rubber Scale) and
504 (Outdoor Gas Power Scale) from
Scale Contest Board jurisdiction to the
Free Flight Contest Board jurisdiction. The
events would also move to the Free Flight
category in the Competition Regulations.
Logic behind proposed change: The Free
Flight Outdoor Scale events are all but
dead, while events such as Flying Aces
Club events continue to grow in
popularity. In 2002 the Nats was one of the
only events to offer AMA Free Flight
Scale events; other events offered FAC
Scale. The Scale Contest Board is
composed of people who are experts in
controlled flight but have little experience
with the issues facing the Free Flight
community.

necessitates an increase in line size, pull test, or both, any changes will be
published concurrently with announcement of new record.
In the case of a record established on a newly increased line size, whereby the
previous pull test standard exceeds the need of the new record, the CLSCB
Chairman will establish a new appropriate pull test standard. For all classes
that have 48G and higher pull tests, the new standard will be no less than 48G.

1. PREFACE
The purpose of this Scale Aerobatics Flying and Judging Guide is to provide
an accurate description of each type of maneuver used in competition and to
provide a reference for use in developing a uniformly high standard of
judging in all AMA sanctioned contests. Study of this guide by the
competitor will help him or her learn exactly what is expected, while study
by the judges will help them decide precisely how well the competitor meets
these expectations.
Flying and judging are very similar in nature; this is why contestant judging
is generally promoted. Nevertheless, there are some key differences between
judges and pilots, mostly related to Mental Attitude and Technical
Knowledge. Reference to any gender in this document shall include both
male and female.

RCA-05-35: Page 91, paragraph 2 Delete:
Scale Aerobatics maneuvers also use the standard K-factors defined by the
FAI, but with two exceptions:
1) The FAI K-Factors for Rolling circle maneuvers (Family 2.3 to 2.20) must
be doubled (i.e.: A FAI K-factor of 13 should become 26).
2) The FAI K-Factor for Tailslide maneuvers (Family 6) must be multiplied
by one and half (1.5) (i.e.: a FAI K-Factor of 16 should become 24). When
the original FAI K-Factor is an odd number, the result of the multiplication
used should be reduced to the lower whole number (i.e.: a FAI K-Factor of
15 should become 22, or 15+7.5=22.5, reduced to the lower number=22).

3. RULES
Scale Aerobatics has several rules that differ from either Full Scale
Aerobatics (IAC) or AMA RC Aerobatics (AMA Pattern). Because the
judging pool used in Scale Aerobatics contests sometimes comes from both
or either of those two groups, it is useful to go through the major differences:
Submitted by: Thomas Wheeler, AMA 405590
RCA-05-37: Page 92, change as follows:
4. RCA-05-37: Positioning
Scale Aerobatics requires all scored maneuvers to be flown in front of the
judges, in an area called the “box”. Competitors should perform their
sequence within the aerobatic box balance about the center of the x-axis and
at an optimal distance from the judges. Judges will give the position grade
according to the total impression of the balanced use of the aerobatic box and
the overall presentation of the sequence. It is not required, however, to use all
the available airspace vertically or on the x or y-axis. As a judge, what is
important is that you apply the same presentation criteria in consistent
manner to every pilot flying the program. The range of possible scores is
from 10 to 0 in .5 increments.
If the sun is positioned such that it hampers positioning and judging of any
maneuvers, the contestant may request the judges to allow an offset of certain
maneuvers. This agreement shall take place prior to the start of the flight.
Also, flying the figures in the front or the back of the box while on the X-axis
is not a criterion for judging. Before entering the box, the pilot or caller
should announce to the judges the direction of flight (Left-to-Right or Rightto-
Left). This is completely the pilot’s option and independent of the wind
direction. Once this announcement is made, the relationship and positioning
between maneuvers is defined by the Aresti sequence drawing.
Category Positioning coefficients are as follows:
Basic 5K
Sportsman 10K
Intermediate 15K
Advanced 20K
Unlimited 25K

RCA-05-38: Page 92
4.1 Scale Aerobatic Box
Two (2) horizontal lines, 90 degrees to each side of the centerline. The total
length of the box shall be 2000 feet (610 meters) along a line parallel to the
flight line. The rear boundary of the box shall be a line parallel to the flight
line and 1000 feet (305 meters) from the competitors position.
Whenever the “complete aircraft” is observed to fly past any boundary, an
infringement penalty will be noted by the maneuver score being circled by
the judge. It should be noted that the judges could disagree on box
infringements (i.e. one judge circles the maneuver and the other doesn’t). The
penalty will be assessed when the scores are tabulated and vary by the class
flown:
i. Basic = two (2) points per infringement
ii. Sportsman = four (4) points per infringement
iii. Intermediate = six (6) points per infringement
iv. Advanced = eight (8) points per infringement
v. Unlimited = ten (10) points per infringement
Because the judges are located behind the pilot, the only box infringements
generally noted are the one that can easily be assessed using the 90 degree
markers reference on the ground. Although judging the side and back
infringements are more difficult due to the lack of references, judges should
still take them into account if the aircraft clearly goes past these boundaries.
In case of uncertainty, always give the competitor the benefit of the doubt.

RCA-05-43: New Event. Indoor RC Aerobatics.
It is the intention to provide a safe aerobatic event for electric powered
models that will be flown indoors. Wherever possible, the rules will be the
same as outdoor radio control pattern. Rather than reproduce the entire set
of pattern rules, the exceptions will be noted.
4. Model aircraft requirements.
4.1 Power. Models shall be powered by battery powered electric
motors. The maximum battery voltage shall be 9.6 volts (manufacturers
ratings). No limit is placed on the number of motors, but the maximum
power delivered to the motor(s) shall be 30 watts. In cases where there is a
question, the contestant may be required to sign an affidavit stating that his
entry conforms to this rule.
4.2 Weight and size. No model shall weigh more than 7 ounces ready to
fly.
1.5 Change radius of spinner tip to 2 millimeters.
7. Pattern event classes.
The indoor pattern event shall be divided into two classes. The first, (class
I) shall be open to any model design that meets the weight and power
criteria. The second (class II) will be limited to models which clearly
resemble an aircraft used in aerobatic competition. This includes outdoor
pattern event models as well as full scale aircraft. Both classes will fly the
same maneuver pattern.
8. Contestant classification. This system will not be used in indoor
aerobatics. Delete sections 8.-8.3.
10. Official flight. Change time limit to two (2) minutes.
11. Time limits. Change time to (2) minutes.
14. The CD will determine the boundary limits for the “box” based on site
conditions, as well as the distance from the judges for the flight path of
maneuvers.
16. Both indoor classes will use the intermediate pattern maneuver
schedule.
20.7 Delete references to weather.
20.8 Delete references to the sun.

Exact wording proposed for the rulebook:
Under section 16.3.1 Airframe:
The airframe specifications for this event are identical to those for Quickie
500 (Event No. 428).
New exact wording of section 16.3.1
The airframe specifications for this event are identical to those for
Quickie 500 (Event No. 428) with the following exceptions: Wing and
tail construction. Wings must be constructed of either all wood or wood
sheeting over a solid foam core. Wings manufactured in molds designed
to produce hollow core composite wings, is prohibited. The last three
inches of each wing tip may be made of any material. The intent of the
rule is to keep the cost of participation to a minimum.

RCR-05-2, page 123, 16.3.2 Powerplant.
Under section 16.3.2 Powerplant, sub-section A. Engine. Remove the
following sentence from item #6 Power Output:
As such, it is not a suitable event for the use of engines that some with
tuned mufflers or otherwise are capable of turning a stock 9 x 6 APC
propeller at over 16, 500 rpm on the ground.
Reword paragraph 6:
“Sport Quickie is intended as an entry-level event for pilots who are
new to racing. Sample engines are tested via committee and a list of
permissible engines is published and updated as necessary, annually.
Criteria include purchase price and power output in both the normal
takeoff RPM range and the presumed in-air (“unloaded”) RPM range.
Any engine with a tuned muffler is strictly prohibited. The cost of the
engine must be below $120 (street price). If engines more powerful than
this are to be used at a contest, the contest should be sanctioned as
Quickie 500 (Event No. 428), not sport Quickie.”
Add paragraph 7:
“Prior approval of engines”.
a). Procedure: All engines, past and future inclusive, shall not be
entered into competition until a five-member sub-committee of the RC
Racing Contest Board has approved the engine by an affirmative vote of
at least three members thereof. Such approval may be given orally, but
shall be recorded for future reference. An engine shall be considered
eligible for competition if it meets all requirements of section 16.3.2
and, in addition, does not hinder the state of this entry level event as
determined by the aforementioned five-member committee. The
committee is appointed by the Racing Contest Board Chairman and will
not include any member with a vested interest in the sale of
manufacturing of an engine for this event. In addition any engine can be
removed from the list by an affirmative vote of at least three members
thereof.
Under section 16.3.3. Special Provisions, sub-section b. Rule Variations
Permitted: Remove item #1: Approval engine list: Sample engines are
tested and a list of permissible engines is published annually. Criteria
include purchase price and power output in both the normal takeoff rpm
range and the presumed in-air (“unloaded”) rpm range.
Remove item #2: Prohibited Features: Typically these include
Schneurle porting and ABC/AAC metallurgy.

SO-05-1. Add the following paragraphs to page 137.
Note: conflicts with proposal with SO-05-2
1.1 No object, device in its fully extended position, or part thereof can
protrude ahead of the nose of the aircraft.
1.2 Ahead of the leading edge of the wing, no part of an object or device in
its fully extended position can protrude more than one inch below the bottom
of the fuselage. If the fuselage bottom is curved, the length of the protrusion
or part thereof will be measured along the perpendicular to a tangent to the
fuselage at the point where the measurement is to be made. 1.3 From the
leading edge of the wing to the rearmost part of the fuselage, no part of an
object or device in its fully extended position can protrude more than three
inches below the bottom of the wing or an extension thereof. Measurements
will be made along a perpendicular to the bottom of the wing at the point in
question. In the event that an object/device is located behind the trailing edge
of the wing, the extension of the bottom of the sing will be determined by
placing a straight edge so that it is in contact with at least two points along
the bottom of the wing and measuring along a perpendicular to the side of the
straight edge that is in contact with the bottom of the wing. Flaps must be
fully retracted when measurements are made.
1.4 The forward facing edge of an object or device in its fully extended
position must have a radius of a t least 0.25 inch in the vertical plane.
1.5 All objects or devices in their fully extended position must lay in a single
plane that is perpendicular to the bottom surface of the wing and congruent
with the centerline of the fuselage.
1.6 The above rules do not apply to those classes that specifically prohibit the
use of devices whose intent it is to produce a rapid deceleration when
landing.

SCA-05-2, Add new event: Control Line Fun Scale
The intent of Fun Scale is to provide a CL Scale event, which is, and is to
remain, simple in concept. It minimizes the static judging and emphasizes the
flying segment.
1. ELIGIBILITY. The contest is open to modeler-built or factory built
CL Scale models. The event rules are identical to event #509, Control Line
Sport Scale except for static judging. General rule 4 (builder — flier) will
not apply in this event. With advance notice, the event may be conducted
in different classes based on skill or age level, i.e., Open, Entry, Junior,
Senior, etc.
2. STATIC JUDGING. The static scale outline score will be a graduated
zero (0) to five (5) points to contestants who show proof that a full size
aircraft or this type did/does exist. An additional score of a graduated zero (0)
to (5) points will be awarded if proof is shown as to replicating a
color/markings scheme of the original full size aircraft. A single sheet (3-
view drawing, photo, profile, painting, plastic kit box, etc.) is sufficient.
Contestant prepared drawings of a photo of the model itself is not acceptable.
If no proof of existence or color/markings is shown, no static points will be
awarded. However, it will be up to the contest director and/or event director
to determine if the scale model is indeed a replica of a full size aircraft of r
contest
eligibility.
3. FLYING. All rules as per CL Sport Scale (event #509).
4. SCORING. The official score shall be the total of static points (10
maximum) and the single best flight score (100 maximum) for a total of 110
points.

Re-number 2.8 to 2.6.
Add new section 3. Outdoor Events
3.1. There are no restrictions as to types of power plants that may be used in
R/C Sport Scale models that are flown outdoors. Reciprocating internal
combustion engines (including 2-stroke, 4-stroke, glow, gas, CO2,
compressed air), electric motors, and turbojet engines are allowed.
3.2. (same as old section “2.7. Turbojet engines “
3.3. With the exception of electric motors, the engine(s) must be equipped
with an effective muffler or silencer to limit noise output. A tuned pipe is
considered a muffler.
3.4. R/C Sport Scale models that are flown outdoors shall weigh no more
than 55 pounds, ready for flight, including fuel.
Add a new section 4. Indoor Events
4.1. R/C Sport Scale models that are flown indoors must be powered with
electric, CO2, orcompressed air motor(s). No other type of power plant is
permissible for indoor flying.
4.2. R/C sport Scale models that are flown indoors shall weigh no more than
12 ounces ready for flight, including fuel or batteries.
4.3. Maximum wing loading of the model, ready for flight, shall not exceed 6
ounces per square foot.
4.4. Due to wide variations in the size and shape of indoor flying sites, the
Contest Director has authority to adjust sections 4.2. and 4.3. as needed to fit
the contest flying site and local conditions. In all cases, any deviation from
these rulebook specifications must be noted in all pre-contest announcements
and literature well in advance of the event.
4.5. Because of the size restrictions that indoor flying naturally imposes on
the flight of a model, the Contest Director has authority to adjust any of the
maneuver descriptions in the “Radio Control Scale Flight Judging Guide” to

Past should be flown between 10 — 20 feet altitude for at least 5 seconds. At
many indoor flying facilities that would be impossible. In all cases, any
deviation from the Judging Guide maneuver descriptions must be noted in all
pre-contest announcements and literature well in advance of the event.

ECL-05-1 page 186 Adds new event: Elexaco
Summary of Elexaco Competition Rules: (Old Timer or Open) The
investment flying electric using a 400 motor is nominal as an existing radio
with at least 3 channels is all that is needed. What makes it real interesting is
that the performance of a 7 cell battery pak with a direct 400 motor system is
outstanding. Using alkaline battery cells in the Tx makes the model always
available for flight when stored in the trunk of your car. Due to the small size
it is stored assembled. In traveling where a field is sited (A football field will
do) simply stop, charge the flight battery for motor and RX power by BEC
and fly as the alkalines for the TX are always ready. Now to add interest a
simple endurance competitive event was designed that can be decided at the
flying field. All that is required is a stop watch. To establish equity the
Elexaco event is offered making it easy as it defines specifically the
hardware required. It is designed as an electric version of the ever popular
1⁄2A Glo-Powered Texaco event and can be restricted to old-timer if desired
by option.
Elexaco Event Rules
1. Any model with an aspect wing ratio of less than 7 qualifies (wingspan
divided by center chord).
03sig6.QXD 12.20.02 11:17 am Page 183

2. Any rated 400 Electric ferrite motor (not brushless or cobalt and not geared)
qualifies.
3. A 7 cell 250 to 350 MAH power pak must be used.
4. Any motor shut off device is acceptable.
Flight Rules
Timed from either take-off or hand launch, motor is allowed to fun for 2 minutes
and shut off by radio—if motor is shut off prior to 2 minutes it is not to be turned
back on—if turned back on score is 0. Flight is continued and timed toward max
flight time of 15 minutes to land at designated field. Score 1 point per second
(max 900 points). Exceeding max results in penalty of 1 point per second.
