I WILL LEAD with the material I promised
in my last column regarding my little
Catapult Glider project. You may recall that
I had received one of the nice Jim Walker
404 Interceptor folding-wing gliders from
Frank Macy. Frank offers reproductions of
the classic RTF FF models that once
appeared under the American Junior banner
(see source listing for details).
The folding-wing Catapult Interceptor
glider seemed to be a perfect candidate to
develop into an RC small-field flyer. The
micro gear we have available today opens
the door to almost any project.
My goal with this project was to develop
something that would be pure fun. I had no
aspirations of a killer thermal machine. I
only wanted to be able to enjoy a classic
model without having to travel to a location
suitable for letting the model fly at its full
potential as an FF aircraft.
By adding micro radio gear, it would be
possible to really pull back on the rubber
catapult launcher and still keep the little
airplane safely in my confined flying
space—a fairly large back yard. With this
objective in mind, the project was launched.
(Yes, that was a weak pun.)
An interesting feature of Frank’s 404
Interceptor is the way he set up the foldingwing
mechanism. The original used a wire
hoop and an aluminum pivot. Frank
engineered a plastic mechanism that actually
You can see the basic equipment installation on the author’s American Junior 404
Interceptor small-field RC conversion project. This is a pure-fun model!
How do the folding wings fair with the added components and linkages? Even with the
wings folded, there is plenty of clearance for the control linkages.
allows a smoother transition between folded
wings for launching to unfolded for gliding.
This plastic wing mount also makes it
possible to easily remove the wings from the
fuselage. That’s a nice feature when you want
to start adding components that were never
intended to be carried on such a model.
With the wings removed, it was fairly
easy to decide where to locate the
components and actually do the installation.
Because they are so light and especially easy
to install on a profile fuselage, I elected to use
magnetic actuators. The units I selected were
the miniature actuators from Bob Selman.
These are well made and weigh
approximately 1 gram each.
Although only installing a rudder would
have been fine, I also added elevator. What
the heck? This was to be a pure-fun model.
Who knows what I might be able to do? The
photo shows the basic equipment installation.
The actuators fit the thickness of the fuselage
perfectly.
For a receiver I used one of the micro
units available from Dynamic Web
Enterprises. Its RFFS-100 is not narrow
band, but since I would be flying in my back
yard, that was not an issue. You could also
use the narrow-band JMP receiver. It is
nearly the same weight as the RFFS-100.
All that was left was a battery. Since I
would not be running a motor with the
battery, I could use the lightest available.
There are roughly 20 mAh Li-Poly units now
on the market, although I ended up using a
much larger battery. It helped balance the
model, but there was another reason for my
choice of a 190 mAh Li-Poly cell.
At the time the model was developed, I
was planning to attend the annual National
Indoor Remote-controlled Aircraft Council
(NIRAC) championships. The converted
Interceptor was to be flown in Indoor Glider
Duration. That event has a maximum
wingspan limit of 30 inches and a minimum
weight requirement of 30 grams. I needed the
weight of the larger battery to help get the
model up to minimum weight, and I certainly
get a lot of flights on one charge.
The unmodified model weighs 20.6
grams. This includes a 3.5-gram steel ball in
the nose to get the proper CG. The RFFS-100
09sig3QXD 6/24/04 8:39 am Page 83
84 MODEL AVIATION
receiver weighs slightly less than 2 grams.
Adding the two 1-gram actuators only
exceeded the weight of the nose ballast by .5
gram.
You can see my dilemma in getting the
model up to minimum weight for the NIRAC
event. The 190 mAh Li-Poly cell weighs 5
grams. Adding carbon-fiber pushrods and
related stuff brought the total weight to 28
grams. Additional weight was still required to
reach the 30-gram minimum, but at least
most of the added weight was functional.
You might wonder how the folding wings
faired with the added components and
linkages. The picture of the bottom of the
model answers this question. The clearance
created from the pivot point when the wings
are folded provides plenty of room for the
linkages. The wings also fold with the tips
elevated above the rear of the fuselage. This
allows the rudder horn to be below the wings
in their folded position. Everything worked
out as I planned—as if I planned. No luck
involved here!
Did I get my desired result? You bet!
From the first launch I had a big grin on my
face. It is a real circus to hold the transmitter
between my legs so I can use both hands to
launch the model. Once in flight, I drop the
rubber sling and grab the transmitter. The
timing is approximately what is needed for
the model to reach full height.
My technique is still developing, but I
have plenty of charge left on that big battery
to practice. Li-Poly cells have a low selfdischarge
rate, so I have no idea how many
flights I still have available on the first
charge.
Flight duration is not yet what I would
like. I need to tune the rubber band that is
used to unfold the wings when the model
reaches maximum height. I find that the
wings tend to delay the deployment phase
until the model has passed the maximum
height, but that has not detracted from the fun
factor.
It is great to be able to launch the model,
fly a few circuits, and then do it all over
again. The converted Interceptor really brings
the kid out in this old modeler.
As I noted in the last column, I have a few
other projects along this line in mind. As the
opportunity arises to work on those projects, I
will be sure to share the results.
Throughout the many years that I have
enjoyed this great hobby, I have lived in
several regions of the country, allowing me to
make many modeling friends. It has also
given me the opportunity to meet some of the
hobby “notables.”
One such person is Al Backstrom. Our
paths cross occasionally at flying events held
in Texas. Al is a master designer and
craftsman. He has shared several of his
projects with us through this column and I’m
Another beauty from Al Backstrom is the MiniMax: an electricpowered
RC model that is perfect for small-field flying.
Bryan Robbins was quite successful in building this nice
Guillow’s Dauntless conversion from the kit materials.
The Nemesis 3D design has been updated to the 3D-II by its new
owner, Randy Roman of Model Airplane Engineering.
AstroFlight 010 fan Irvin Cooper has created an information
section on his Web site about the brushless motor.
09sig3QXD 6/24/04 8:39 am Page 84
pleased that he has done so again.
Al has taken a nice, lightweight, fullscale,
home-built design known as the
MiniMax and rendered it an alluring
electric-powered RC model that is perfect
for small-field flying. The picture of the
model certainly excites me.
The specifications of the aircraft include
a 30-inch wingspan, a 165-square-inch wing
area, a 5.5-ounce flying weight, a GWS IPSDXA
motor with a 7 x 6 propeller, and two
340 mAh Li-Poly cells in series. The flying
surfaces are covered with yellow Litespan
and the fuselage is covered with blue
Japanese tissue. The markings are based on
a full-scale MiniMax.
This is a nice model. As of this writing,
Al had not decided about plans availability.
If I hear anything, I will be sure to let you
know.
I have been happy with the responses I have
received following my observations about
the suitability of the Guillow’s designs for
conversion to small-field RC aircraft. Two
modelers located in Vancouver,
Washington, wrote that they have had great
success converting Guillow’s kits.
Eric Molstead and Bryan Robbins
wanted to let us know of their experience
using Guillow’s kits as a source for Scale
small-field flyers. Eric sent some nice
pictures of the Guillow’s Dauntless that
Bryan converted to a great-flying, electricpowered
small-field flyer. I wish I had room
to share more than one photo. This is a very
nice airplane.
When Bryan built the model, he used the
wood supplied in the kit. Material was
removed where possible to help reduce the
weight, but he was quite successful in
getting a nice-flying aircraft built from the
kit materials.
The power comes from a PJS 300
external-rotor brushless motor available
from Hobby Lobby. The motor is controlled
using a Castle Creations Phoenix-10 ESC.
Energy comes from two Li-Poly cells in
series. Control functions include throttle,
rudder, elevator, and bomb drop. The model
is covered with lightweight, opaque
Oracover. The total flying weight is 11
ounces.
Great effort, Bryan and Eric! Be sure to
let us know about any future Guillow’s
conversion projects.
Several columns ago I offered a few
comments about the emerging offerings for
great-performing 3-D aerobatic-capable
models in the small-field arena. One I
mentioned was the Nemesis 3D. At the time
that column was written, the kit was offered
by Aero Lock Models. A note from Randy
Roman of Model Airplane Engineering let
me know that he has acquired the Nemesis

3D design. Randy has reengineered the
structure of the model to gain strength with
no additional weight.
The Nemesis 3D-II is a nice laser-cut kit
that goes together quickly. For those
wanting to get into the small-field 3-D
aerobatics scene, this model might just be
the ticket. It has a wide range of power
options that start with readily available and
reasonably priced brushed motors in
combination with a GWS gear drive.
The kit will also accept the “outrunner”
brushless motors that are becoming so
popular. To make it easy to fit the trendy
outrunner-style motors to the Nemesis 3DII,
Randy offers laser-cut plywood mounts
designed for them. These mounts make it a
snap to switch between the brushed
motor/GWS gearbox setup to one of the
outrunner brushless installations.
With a 27-inch wingspan and a flying
weight that falls between 4.5 and 6.5
ounces, the Nemesis 3D-II is perfect for
small-field flying.
I want to share information about one more
picture with you. Irvin Cooper is a big fan
of the AstroFlight 010 brushless electric
motor. In the picture you see him with his
Astro 010-powered Tumble Watt, designed
by Tom Hunt. Irv reports that this is a great
combination that gives a satisfying
performance.
Irv is such a fan of the Astro 010 that he
has developed a nice information section
within his Web site covering the motor and
associated models. The Astro 010 brushless
motor helped pioneer the smaller highperformance
electric motors and is still a
viable power option for our small-field
models.
If you have access to the Internet, take a
look at Irv’s site at www.cpinternet.com/
~mmmpc535. Navigate to the section
devoted to the Astro 010.
If anyone is likely to be in the Dallas or
Houston, Texas, area in October, there are
two great flying gatherings scheduled. The
18th annual Dallas Electric Aircraft Flyers
(DEAF) fly-in is planned for October 2-3.
For more information, see the DEAF Web
site at www.deaf-rc.org/.
Following that, the Barnstormers club of
New Waverly, Texas, has scheduled its allelectric
fly-in for October 8-10. More details
can be found on the Barnstormers’ Web site
at www.tri-countybarnstormers.com. I plan
to attend both events and would be pleased
if any readers looked me up to say hello.
Here we are at the end once again. As
always, please send in a picture or two of
your models so we can all enjoy them. MA

MiniMax and rendered it an alluring
electric-powered RC model that is perfect
for small-field flying. The picture of the
model certainly excites me.
The specifications of the aircraft include
a 30-inch wingspan, a 165-square-inch wing
area, a 5.5-ounce flying weight, a GWS IPSDXA
motor with a 7 x 6 propeller, and two
340 mAh Li-Poly cells in series. The flying
surfaces are covered with yellow Litespan
and the fuselage is covered with blue
Japanese tissue. The markings are based on
a full-scale MiniMax.
This is a nice model. As of this writing,
Al had not decided about plans availability.
If I hear anything, I will be sure to let you
know.
I have been happy with the responses I have
received following my observations about
the suitability of the Guillow’s designs for
conversion to small-field RC aircraft. Two
modelers located in Vancouver,
Washington, wrote that they have had great
success converting Guillow’s kits.
Eric Molstead and Bryan Robbins
wanted to let us know of their experience
using Guillow’s kits as a source for Scale
small-field flyers. Eric sent some nice
pictures of the Guillow’s Dauntless that
Bryan converted to a great-flying, electricpowered
small-field flyer. I wish I had room
to share more than one photo. This is a very
nice airplane.
When Bryan built the model, he used the
wood supplied in the kit. Material was
removed where possible to help reduce the
weight, but he was quite successful in
getting a nice-flying aircraft built from the
kit materials.
The power comes from a PJS 300
external-rotor brushless motor available
from Hobby Lobby. The motor is controlled
using a Castle Creations Phoenix-10 ESC.
Energy comes from two Li-Poly cells in
series. Control functions include throttle,
rudder, elevator, and bomb drop. The model

Oracover. The total flying weight is 11
ounces.
Great effort, Bryan and Eric! Be sure to

3D design. Randy has reengineered the
structure of the model to gain strength with
no additional weight.
The Nemesis 3D-II is a nice laser-cut kit
that goes together quickly. For those
wanting to get into the small-field 3-D
aerobatics scene, this model might just be
the ticket. It has a wide range of power
options that start with readily available and
reasonably priced brushed motors in
combination with a GWS gear drive.
The kit will also accept the “outrunner”
brushless motors that are becoming so
popular. To make it easy to fit the trendy
outrunner-style motors to the Nemesis 3DII,
Randy offers laser-cut plywood mounts
designed for them. These mounts make it a
snap to switch between the brushed
motor/GWS gearbox setup to one of the
outrunner brushless installations.
With a 27-inch wingspan and a flying
weight that falls between 4.5 and 6.5
ounces, the Nemesis 3D-II is perfect for
small-field flying.
I want to share information about one more
picture with you. Irvin Cooper is a big fan
of the AstroFlight 010 brushless electric
motor. In the picture you see him with his
Astro 010-powered Tumble Watt, designed
by Tom Hunt. Irv reports that this is a great
combination that gives a satisfying
performance.
Irv is such a fan of the Astro 010 that he
has developed a nice information section
within his Web site covering the motor and
associated models. The Astro 010 brushless
motor helped pioneer the smaller highperformance
electric motors and is still a
viable power option for our small-field
models.
If you have access to the Internet, take a
look at Irv’s site at www.cpinternet.com/
~mmmpc535. Navigate to the section
devoted to the Astro 010.
If anyone is likely to be in the Dallas or
Houston, Texas, area in October, there are
two great flying gatherings scheduled. The
18th annual Dallas Electric Aircraft Flyers
(DEAF) fly-in is planned for October 2-3.
For more information, see the DEAF Web
site at www.deaf-rc.org/.
Following that, the Barnstormers club of
New Waverly, Texas, has scheduled its allelectric
fly-in for October 8-10. More details
can be found on the Barnstormers’ Web site
at www.tri-countybarnstormers.com. I plan
to attend both events and would be pleased
if any readers looked me up to say hello.
Here we are at the end once again. As
always, please send in a picture or two of
your models so we can all enjoy them. MA

I WILL LEAD with the material I promised
in my last column regarding my little
Catapult Glider project. You may recall that
I had received one of the nice Jim Walker
404 Interceptor folding-wing gliders from
Frank Macy. Frank offers reproductions of
the classic RTF FF models that once
appeared under the American Junior banner
(see source listing for details).
The folding-wing Catapult Interceptor
glider seemed to be a perfect candidate to
develop into an RC small-field flyer. The
micro gear we have available today opens
the door to almost any project.
My goal with this project was to develop
something that would be pure fun. I had no
aspirations of a killer thermal machine. I
only wanted to be able to enjoy a classic
model without having to travel to a location
suitable for letting the model fly at its full
potential as an FF aircraft.
By adding micro radio gear, it would be
possible to really pull back on the rubber
catapult launcher and still keep the little
airplane safely in my confined flying
space—a fairly large back yard. With this
objective in mind, the project was launched.
(Yes, that was a weak pun.)
An interesting feature of Frank’s 404
Interceptor is the way he set up the foldingwing
mechanism. The original used a wire
hoop and an aluminum pivot. Frank
engineered a plastic mechanism that actually
You can see the basic equipment installation on the author’s American Junior 404
Interceptor small-field RC conversion project. This is a pure-fun model!
How do the folding wings fair with the added components and linkages? Even with the
wings folded, there is plenty of clearance for the control linkages.
allows a smoother transition between folded
wings for launching to unfolded for gliding.
This plastic wing mount also makes it
possible to easily remove the wings from the
fuselage. That’s a nice feature when you want
to start adding components that were never
intended to be carried on such a model.
With the wings removed, it was fairly
easy to decide where to locate the
components and actually do the installation.
Because they are so light and especially easy
to install on a profile fuselage, I elected to use
magnetic actuators. The units I selected were
the miniature actuators from Bob Selman.
These are well made and weigh
approximately 1 gram each.
Although only installing a rudder would
have been fine, I also added elevator. What
the heck? This was to be a pure-fun model.
Who knows what I might be able to do? The
photo shows the basic equipment installation.
The actuators fit the thickness of the fuselage
perfectly.
For a receiver I used one of the micro
units available from Dynamic Web
Enterprises. Its RFFS-100 is not narrow
band, but since I would be flying in my back
yard, that was not an issue. You could also
use the narrow-band JMP receiver. It is
nearly the same weight as the RFFS-100.
All that was left was a battery. Since I
would not be running a motor with the
battery, I could use the lightest available.
There are roughly 20 mAh Li-Poly units now
on the market, although I ended up using a
much larger battery. It helped balance the
model, but there was another reason for my
choice of a 190 mAh Li-Poly cell.
At the time the model was developed, I
was planning to attend the annual National
Indoor Remote-controlled Aircraft Council
(NIRAC) championships. The converted
Interceptor was to be flown in Indoor Glider
Duration. That event has a maximum
wingspan limit of 30 inches and a minimum
weight requirement of 30 grams. I needed the
weight of the larger battery to help get the
model up to minimum weight, and I certainly
get a lot of flights on one charge.
The unmodified model weighs 20.6
grams. This includes a 3.5-gram steel ball in
the nose to get the proper CG. The RFFS-100
09sig3QXD 6/24/04 8:39 am Page 83
84 MODEL AVIATION
receiver weighs slightly less than 2 grams.
Adding the two 1-gram actuators only
exceeded the weight of the nose ballast by .5
gram.
You can see my dilemma in getting the
model up to minimum weight for the NIRAC
event. The 190 mAh Li-Poly cell weighs 5
grams. Adding carbon-fiber pushrods and
related stuff brought the total weight to 28
grams. Additional weight was still required to
reach the 30-gram minimum, but at least
most of the added weight was functional.
You might wonder how the folding wings
faired with the added components and
linkages. The picture of the bottom of the
model answers this question. The clearance
created from the pivot point when the wings
are folded provides plenty of room for the
linkages. The wings also fold with the tips
elevated above the rear of the fuselage. This
allows the rudder horn to be below the wings
in their folded position. Everything worked
out as I planned—as if I planned. No luck
involved here!
Did I get my desired result? You bet!
From the first launch I had a big grin on my
face. It is a real circus to hold the transmitter
between my legs so I can use both hands to
launch the model. Once in flight, I drop the
rubber sling and grab the transmitter. The
timing is approximately what is needed for
the model to reach full height.
My technique is still developing, but I
have plenty of charge left on that big battery
to practice. Li-Poly cells have a low selfdischarge
rate, so I have no idea how many
flights I still have available on the first
charge.
Flight duration is not yet what I would
like. I need to tune the rubber band that is
used to unfold the wings when the model
reaches maximum height. I find that the
wings tend to delay the deployment phase
until the model has passed the maximum
height, but that has not detracted from the fun
factor.
It is great to be able to launch the model,
fly a few circuits, and then do it all over
again. The converted Interceptor really brings
the kid out in this old modeler.
As I noted in the last column, I have a few
other projects along this line in mind. As the
opportunity arises to work on those projects, I
will be sure to share the results.
Throughout the many years that I have
enjoyed this great hobby, I have lived in
several regions of the country, allowing me to
make many modeling friends. It has also
given me the opportunity to meet some of the
hobby “notables.”
One such person is Al Backstrom. Our
paths cross occasionally at flying events held
in Texas. Al is a master designer and
craftsman. He has shared several of his
projects with us through this column and I’m

3D design. Randy has reengineered the
structure of the model to gain strength with
no additional weight.
The Nemesis 3D-II is a nice laser-cut kit
that goes together quickly. For those
wanting to get into the small-field 3-D
aerobatics scene, this model might just be
the ticket. It has a wide range of power
options that start with readily available and
reasonably priced brushed motors in
combination with a GWS gear drive.
The kit will also accept the “outrunner”
brushless motors that are becoming so
popular. To make it easy to fit the trendy
outrunner-style motors to the Nemesis 3DII,
Randy offers laser-cut plywood mounts
designed for them. These mounts make it a
snap to switch between the brushed
motor/GWS gearbox setup to one of the
outrunner brushless installations.
With a 27-inch wingspan and a flying
weight that falls between 4.5 and 6.5
ounces, the Nemesis 3D-II is perfect for
small-field flying.
I want to share information about one more
picture with you. Irvin Cooper is a big fan
of the AstroFlight 010 brushless electric
motor. In the picture you see him with his
Astro 010-powered Tumble Watt, designed
by Tom Hunt. Irv reports that this is a great
combination that gives a satisfying
performance.
Irv is such a fan of the Astro 010 that he
has developed a nice information section
within his Web site covering the motor and
associated models. The Astro 010 brushless
motor helped pioneer the smaller highperformance
electric motors and is still a
viable power option for our small-field
models.
If you have access to the Internet, take a
look at Irv’s site at www.cpinternet.com/
~mmmpc535. Navigate to the section
devoted to the Astro 010.
If anyone is likely to be in the Dallas or
Houston, Texas, area in October, there are
two great flying gatherings scheduled. The
18th annual Dallas Electric Aircraft Flyers
(DEAF) fly-in is planned for October 2-3.
For more information, see the DEAF Web
site at www.deaf-rc.org/.
Following that, the Barnstormers club of
New Waverly, Texas, has scheduled its allelectric
fly-in for October 8-10. More details
can be found on the Barnstormers’ Web site
at www.tri-countybarnstormers.com. I plan
to attend both events and would be pleased
if any readers looked me up to say hello.
Here we are at the end once again. As
always, please send in a picture or two of
your models so we can all enjoy them. MA

I WILL LEAD with the material I promised
in my last column regarding my little
Catapult Glider project. You may recall that
I had received one of the nice Jim Walker
404 Interceptor folding-wing gliders from
Frank Macy. Frank offers reproductions of
the classic RTF FF models that once
appeared under the American Junior banner
(see source listing for details).
The folding-wing Catapult Interceptor
glider seemed to be a perfect candidate to
develop into an RC small-field flyer. The
micro gear we have available today opens
the door to almost any project.
My goal with this project was to develop
something that would be pure fun. I had no
aspirations of a killer thermal machine. I
only wanted to be able to enjoy a classic
model without having to travel to a location
suitable for letting the model fly at its full
potential as an FF aircraft.
By adding micro radio gear, it would be
possible to really pull back on the rubber
catapult launcher and still keep the little
airplane safely in my confined flying
space—a fairly large back yard. With this
objective in mind, the project was launched.
(Yes, that was a weak pun.)
An interesting feature of Frank’s 404
Interceptor is the way he set up the foldingwing
mechanism. The original used a wire
hoop and an aluminum pivot. Frank
engineered a plastic mechanism that actually
You can see the basic equipment installation on the author’s American Junior 404
Interceptor small-field RC conversion project. This is a pure-fun model!
How do the folding wings fair with the added components and linkages? Even with the
wings folded, there is plenty of clearance for the control linkages.
allows a smoother transition between folded
wings for launching to unfolded for gliding.
This plastic wing mount also makes it
possible to easily remove the wings from the
fuselage. That’s a nice feature when you want
to start adding components that were never
intended to be carried on such a model.
With the wings removed, it was fairly
easy to decide where to locate the
components and actually do the installation.
Because they are so light and especially easy
to install on a profile fuselage, I elected to use
magnetic actuators. The units I selected were
the miniature actuators from Bob Selman.
These are well made and weigh
approximately 1 gram each.
Although only installing a rudder would
have been fine, I also added elevator. What
the heck? This was to be a pure-fun model.
Who knows what I might be able to do? The
photo shows the basic equipment installation.
The actuators fit the thickness of the fuselage
perfectly.
For a receiver I used one of the micro
units available from Dynamic Web
Enterprises. Its RFFS-100 is not narrow
band, but since I would be flying in my back
yard, that was not an issue. You could also
use the narrow-band JMP receiver. It is
nearly the same weight as the RFFS-100.
All that was left was a battery. Since I
would not be running a motor with the
battery, I could use the lightest available.
There are roughly 20 mAh Li-Poly units now
on the market, although I ended up using a
much larger battery. It helped balance the
model, but there was another reason for my
choice of a 190 mAh Li-Poly cell.
At the time the model was developed, I
was planning to attend the annual National
Indoor Remote-controlled Aircraft Council
(NIRAC) championships. The converted
Interceptor was to be flown in Indoor Glider
Duration. That event has a maximum
wingspan limit of 30 inches and a minimum
weight requirement of 30 grams. I needed the
weight of the larger battery to help get the
model up to minimum weight, and I certainly
get a lot of flights on one charge.
The unmodified model weighs 20.6
grams. This includes a 3.5-gram steel ball in
the nose to get the proper CG. The RFFS-100
09sig3QXD 6/24/04 8:39 am Page 83
84 MODEL AVIATION
receiver weighs slightly less than 2 grams.
Adding the two 1-gram actuators only
exceeded the weight of the nose ballast by .5
gram.
You can see my dilemma in getting the
model up to minimum weight for the NIRAC
event. The 190 mAh Li-Poly cell weighs 5
grams. Adding carbon-fiber pushrods and
related stuff brought the total weight to 28
grams. Additional weight was still required to
reach the 30-gram minimum, but at least
most of the added weight was functional.
You might wonder how the folding wings
faired with the added components and
linkages. The picture of the bottom of the
model answers this question. The clearance
created from the pivot point when the wings
are folded provides plenty of room for the
linkages. The wings also fold with the tips
elevated above the rear of the fuselage. This
allows the rudder horn to be below the wings
in their folded position. Everything worked
out as I planned—as if I planned. No luck
involved here!
Did I get my desired result? You bet!
From the first launch I had a big grin on my
face. It is a real circus to hold the transmitter
between my legs so I can use both hands to
launch the model. Once in flight, I drop the
rubber sling and grab the transmitter. The
timing is approximately what is needed for
the model to reach full height.
My technique is still developing, but I
have plenty of charge left on that big battery
to practice. Li-Poly cells have a low selfdischarge
rate, so I have no idea how many
flights I still have available on the first
charge.
Flight duration is not yet what I would
like. I need to tune the rubber band that is
used to unfold the wings when the model
reaches maximum height. I find that the
wings tend to delay the deployment phase
until the model has passed the maximum
height, but that has not detracted from the fun
factor.
It is great to be able to launch the model,
fly a few circuits, and then do it all over
again. The converted Interceptor really brings
the kid out in this old modeler.
As I noted in the last column, I have a few
other projects along this line in mind. As the
opportunity arises to work on those projects, I
will be sure to share the results.
Throughout the many years that I have
enjoyed this great hobby, I have lived in
several regions of the country, allowing me to
make many modeling friends. It has also
given me the opportunity to meet some of the
hobby “notables.”
One such person is Al Backstrom. Our
paths cross occasionally at flying events held
in Texas. Al is a master designer and
craftsman. He has shared several of his
projects with us through this column and I’m
Another beauty from Al Backstrom is the MiniMax: an electricpowered
RC model that is perfect for small-field flying.
Bryan Robbins was quite successful in building this nice
Guillow’s Dauntless conversion from the kit materials.
The Nemesis 3D design has been updated to the 3D-II by its new
owner, Randy Roman of Model Airplane Engineering.
AstroFlight 010 fan Irvin Cooper has created an information
section on his Web site about the brushless motor.
09sig3QXD 6/24/04 8:39 am Page 84
pleased that he has done so again.
Al has taken a nice, lightweight, fullscale,
home-built design known as the
MiniMax and rendered it an alluring
electric-powered RC model that is perfect
for small-field flying. The picture of the
model certainly excites me.
The specifications of the aircraft include
a 30-inch wingspan, a 165-square-inch wing
area, a 5.5-ounce flying weight, a GWS IPSDXA
motor with a 7 x 6 propeller, and two
340 mAh Li-Poly cells in series. The flying
surfaces are covered with yellow Litespan
and the fuselage is covered with blue
Japanese tissue. The markings are based on
a full-scale MiniMax.
This is a nice model. As of this writing,
Al had not decided about plans availability.
If I hear anything, I will be sure to let you
know.
I have been happy with the responses I have
received following my observations about
the suitability of the Guillow’s designs for
conversion to small-field RC aircraft. Two
modelers located in Vancouver,
Washington, wrote that they have had great
success converting Guillow’s kits.
Eric Molstead and Bryan Robbins
wanted to let us know of their experience
using Guillow’s kits as a source for Scale
small-field flyers. Eric sent some nice
pictures of the Guillow’s Dauntless that
Bryan converted to a great-flying, electricpowered
small-field flyer. I wish I had room
to share more than one photo. This is a very
nice airplane.
When Bryan built the model, he used the
wood supplied in the kit. Material was
removed where possible to help reduce the
weight, but he was quite successful in
getting a nice-flying aircraft built from the
kit materials.
The power comes from a PJS 300
external-rotor brushless motor available
from Hobby Lobby. The motor is controlled
using a Castle Creations Phoenix-10 ESC.
Energy comes from two Li-Poly cells in
series. Control functions include throttle,
rudder, elevator, and bomb drop. The model
is covered with lightweight, opaque
Oracover. The total flying weight is 11
ounces.
Great effort, Bryan and Eric! Be sure to
let us know about any future Guillow’s
conversion projects.
Several columns ago I offered a few
comments about the emerging offerings for
great-performing 3-D aerobatic-capable
models in the small-field arena. One I
mentioned was the Nemesis 3D. At the time
that column was written, the kit was offered
by Aero Lock Models. A note from Randy
Roman of Model Airplane Engineering let
me know that he has acquired the Nemesis

popular. To make it easy to fit the trendy
outrunner-style motors to the Nemesis 3DII,
Randy offers laser-cut plywood mounts
designed for them. These mounts make it a
snap to switch between the brushed
motor/GWS gearbox setup to one of the
outrunner brushless installations.
With a 27-inch wingspan and a flying
weight that falls between 4.5 and 6.5
ounces, the Nemesis 3D-II is perfect for
small-field flying.
I want to share information about one more
picture with you. Irvin Cooper is a big fan
of the AstroFlight 010 brushless electric
motor. In the picture you see him with his
Astro 010-powered Tumble Watt, designed
by Tom Hunt. Irv reports that this is a great
combination that gives a satisfying
performance.
Irv is such a fan of the Astro 010 that he
has developed a nice information section
within his Web site covering the motor and
associated models. The Astro 010 brushless
motor helped pioneer the smaller highperformance
electric motors and is still a
viable power option for our small-field
models.
If you have access to the Internet, take a
look at Irv’s site at www.cpinternet.com/
~mmmpc535. Navigate to the section
devoted to the Astro 010.
If anyone is likely to be in the Dallas or
Houston, Texas, area in October, there are
two great flying gatherings scheduled. The
18th annual Dallas Electric Aircraft Flyers
(DEAF) fly-in is planned for October 2-3.
For more information, see the DEAF Web
site at www.deaf-rc.org/.
Following that, the Barnstormers club of
New Waverly, Texas, has scheduled its allelectric
fly-in for October 8-10. More details
can be found on the Barnstormers’ Web site
at www.tri-countybarnstormers.com. I plan
to attend both events and would be pleased
if any readers looked me up to say hello.
Here we are at the end once again. As
always, please send in a picture or two of
your models so we can all enjoy them. MA
