This article will concentrate on
comparing the Optic 6 with an existing

review system. Certain advantages and, in
some cases, disadvantages are highlighted
so you can decide if this is the radio system
for you.)
IF YOU LIKE the Hitec RCD Eclipse 7
RC system, you will surely like the new
Optic 6 system. There are some differences
and similarities between the two. Rest
assured that the Eclipse is not being phased
out. The Optic 6 offers many features at a
price list that is actually lower than the
Eclipse’s.
I’ve owned my Eclipse system for
almost four years. Roughly two years ago
Hitec revised some of the software, and the
added items have appeared on all new
Eclipse transmitters since approximately
March 2003. All of the additional features
on the later Eclipse transmitters have been
included with the new Optic transmitter. I’ll
mention these as new items, but some
newer Eclipse owners already enjoy these
features.
What’s New? For starters, you get an
additional memory position, which means
you will have eight memories instead of
seven. A new Q-PCM (Quick-PCM [Pulse

Hitec RCD Optic 6 Radio System
The complete Hitec Optic 6 RC system includes the Supreme 8 receiver, four HS-325HB
servos, full Ni-Cd batteries, and a charger, for a $209.99 street price.
Popular Hitec Eclipse 7 transmitter (L) has seven channel
functions and seven model memory positions. New Optic 6
transmitter has six channel functions and eight model memory
positions, at a lower price.
Optic 6 transmitter with Spectra synthesized RF module, with Ni-
Cd battery and charger, has $179.99 street price. This version
does not come with airborne components.
Code Modulation]) receiver is now
available, which provides fail-safe and failsafe
presets. The Optic transmitter can be
set for PPM (regular FM, or Pulse Position
Modulation) or PCM.
The three menus for aircraft, glider, and
helicopter have been partially combined;
aircraft and glider are now on one menu
system, and helicopter is on a second.
However, the types of special control
functions remain essentially the same.
When you first turn on the main power
switch, the start-up display momentarily
indicates the model’s name for the current
selected memory position. The extra
channel rotary knobs have been replaced by
54 MODEL AVIATION
two levers that are located on either side of
the case.
The Optic transmitter now has
assignable switches for the landing
function, camber, crow, elevator/flap
mixing, aileron/rudder mixing, and
programmable mixing. The engine
(throttle)-cut switch button is now located
on the upper right corner of the case. There
is also a new “ailevator” function that
allows you to do Torque Rolls with 3-Dtype
aircraft.
Common Features: The Eclipse and the
Optic offer several features that are worth
having. Both transmitters accept the Hitec
Spectra Synthesized RF [radio frequency]
Module, which allows you to select any one
of the 50 RC channels between 72 and 73
MHz. To add even more versatility, the FM
deviation can be selected for “Hi” or “Lo.”
That means almost any brand and type of
FM (PPM) RC receiver can be operated
from the Eclipse or the Optic transmitter.
For years Hitec has employed
nonvolatile memory, which means that the
computer system does not need an internal
backup battery. The transmitter never needs
to go back to the factory for a battery
change, and what is stored in the
microprocessor remains there until you
change it.
A “LOCK” switch is provided on the
Optic transmitter, and it isn’t what you
think! Most people might think it would
prevent unwanted commands or inputs from
being made to the internal computer.
When pressed, the LOCK switch secures
the throttle channel so that a motor doesn’t
inadvertently start or an idling, fueled
engine doesn’t jump to a high throttle
setting. That way, an accidental movement
of the throttle stick while you are in the pit
area or walking out to the flightline will do

nothing. I like that safety feature very
much!
Optic System Choices: Hitec offers five
system versions of the Optic 6. The basic
aircraft system (featured here) is catalog
item 158721. With the Supreme PPM (FM)
receiver, four HS-325HB servos, a switch
harness, full Ni-Cd batteries and charger, an
aileron extension cable, a frequency flag set,
and an instruction manual, it has a street
price of $209.99.
The transmitter alone, with the Spectra
Synthesized RF Module, transmitter Ni-Cd
batteries, and charger has a street price of
$179.99. That is without receiver and
servos.
If you go to www.hitecrcd.com/Radios/
OPTIC.htm, you can see all of the system
options, which will help you when making
your purchase. If you click at the top of the
page on “Manual (PDF),” you will find a
reproduction of the entire 60-page operating
manual. Since the detailed control features
are available there, I won’t get into every
menu item here.
When you purchase a standard Optic
system, the transmitter is supplied with one
RF module of your choice of frequency.
You can purchase separately and substitute
the Spectra synthesized module later, or you
can obtain the transmitter with the Spectra
from the start. All 50 channels are available
on the aircraft frequencies from 72 to 73
MHz. Six-meter frequencies are unavailable
for HAM fliers.
Comments: As do most modern RC
transmitters, the Optic employs digital trim
on the four primary flight channel functions
(aileron, elevator, throttle, and rudder).
Since digital trim is activated by pushbutton
switches, the amount of trim being
employed can’t be determined by visually
looking at a trim lever (as it is on older
transmitters).
When you first power up the Optic’s
transmitter, the model name appears
momentarily, and then the normal display
appears. If you press either “EDIT” button,
you will almost immediately get to “TRIM.”
When the power is first turned on, the first
trim position shown is CH 1 (aileron). If
you haven’t set any trim, it will indicate 0%.
Each time you move the aileron trim lever
left or right, you will add trim 1% at a time.
Applying right aileron trim will cause
the number to go positive, such as +1%,
+2%, etc. Applying the opposite, or left,
trim will cause the number to go negative,
such as +1%, 0%, -1%, -2%, etc.
With the normal display in view,
anytime you press either EDIT button, you
will quickly get to the TRIM position
display. To look at other trim positions such
as elevator and rudder, you must press that
particular trim button. When you do so you
have added 1% elevator trim, and the
previously set elevator trim plus 1% will
show on the screen. After determining the
elevator trim position, you must return it to
1% to get back to your actual trim setting.
It is confusing to describe but easy when
put to use. The only thing you must realize
is that just one trim-function percentage can
be displayed at a time.
The Eclipse transmitter has a separate
dual rate/exponential (expo) rate switch for
aileron, elevator, and rudder (three
switches). On the Optic the elevator and
rudder are combined on one switch (so there
are only two dual rate/expo switches).
When using the Spectra Synthesized RF
Module, you must physically remove the
module and rotate two dials to obtain any
one of the 50 channels of your choice.
The Optic transmitter actually has three
timer functions, one of which is an elapsed
timer that appears on the right side of the
normal display. You are advised to set it to
zero after each battery charging. Then the
timer counts every time you turn on the
transmitter power. This will give you an
idea of cumulative operating time on a
single charge.
The other two timer functions allow you
to set a timed period of one to 60 minutes.
Both of these timer positions will then count
down to zero and sound an alarm (of your
choice).
The Optic 6 system is certainly easy to use.
The menu system takes little skill to
understand and operate. As a beginner,
you can only activate the special controls
you need. I like to see a beginner using
endpoint adjustment so that control throws
(travel) can be tailored to the new pilot’s
skill level. Having to do this using
mechanical adjustments can prove to be
tedious.
I’m also a big fan of expo rate control
since it will allow you to desensitize the
control feel around the neutral position.
Many airplanes “dancing around” in the
sky, with newcomers at the controls, have
been considerably smoothed out using
expo rate control.
I like the Spectra module since you can
easily change frequencies. Although you
must change the crystal at the receiver end
to match your Spectra, it can still be a
bonus when flying at a crowded club field.
The prices of the new Hitec Optic 6
systems are extremely attractive. Refer

(Editor’s note: This is a somewhat new
RC-system-review format. Since so much
detailed information can be obtained from
the manufacturer’s Web site, including a
full copy of the operating manual, our wish
is not to repeat that data and waste
valuable magazine space.
This article will concentrate on
comparing the Optic 6 with an existing
product and identifying new features of the
review system. Certain advantages and, in
some cases, disadvantages are highlighted
so you can decide if this is the radio system
for you.)
IF YOU LIKE the Hitec RCD Eclipse 7
RC system, you will surely like the new
Optic 6 system. There are some differences
and similarities between the two. Rest
assured that the Eclipse is not being phased
out. The Optic 6 offers many features at a
price list that is actually lower than the
Eclipse’s.
I’ve owned my Eclipse system for
almost four years. Roughly two years ago
Hitec revised some of the software, and the
added items have appeared on all new
Eclipse transmitters since approximately
March 2003. All of the additional features
on the later Eclipse transmitters have been
included with the new Optic transmitter. I’ll
mention these as new items, but some
newer Eclipse owners already enjoy these
features.
What’s New? For starters, you get an
additional memory position, which means
you will have eight memories instead of
seven. A new Q-PCM (Quick-PCM [Pulse

Hitec RCD Optic 6 Radio System
The complete Hitec Optic 6 RC system includes the Supreme 8 receiver, four HS-325HB
servos, full Ni-Cd batteries, and a charger, for a $209.99 street price.
Popular Hitec Eclipse 7 transmitter (L) has seven channel
functions and seven model memory positions. New Optic 6
transmitter has six channel functions and eight model memory
positions, at a lower price.
Optic 6 transmitter with Spectra synthesized RF module, with Ni-
Cd battery and charger, has $179.99 street price. This version
does not come with airborne components.
Code Modulation]) receiver is now
available, which provides fail-safe and failsafe
presets. The Optic transmitter can be
set for PPM (regular FM, or Pulse Position
Modulation) or PCM.
The three menus for aircraft, glider, and
helicopter have been partially combined;
aircraft and glider are now on one menu
system, and helicopter is on a second.
However, the types of special control
functions remain essentially the same.
When you first turn on the main power
switch, the start-up display momentarily
indicates the model’s name for the current
selected memory position. The extra
channel rotary knobs have been replaced by

two levers that are located on either side of
the case.
The Optic transmitter now has
assignable switches for the landing
function, camber, crow, elevator/flap
mixing, aileron/rudder mixing, and
programmable mixing. The engine
(throttle)-cut switch button is now located
on the upper right corner of the case. There
is also a new “ailevator” function that
allows you to do Torque Rolls with 3-Dtype
aircraft.
Common Features: The Eclipse and the
Optic offer several features that are worth
having. Both transmitters accept the Hitec
Spectra Synthesized RF [radio frequency]
Module, which allows you to select any one
of the 50 RC channels between 72 and 73
MHz. To add even more versatility, the FM
deviation can be selected for “Hi” or “Lo.”
That means almost any brand and type of
FM (PPM) RC receiver can be operated
from the Eclipse or the Optic transmitter.
For years Hitec has employed
nonvolatile memory, which means that the
computer system does not need an internal
backup battery. The transmitter never needs
to go back to the factory for a battery
change, and what is stored in the
microprocessor remains there until you
change it.
A “LOCK” switch is provided on the
Optic transmitter, and it isn’t what you
think! Most people might think it would
prevent unwanted commands or inputs from
being made to the internal computer.
When pressed, the LOCK switch secures
the throttle channel so that a motor doesn’t
inadvertently start or an idling, fueled
engine doesn’t jump to a high throttle
setting. That way, an accidental movement
of the throttle stick while you are in the pit
area or walking out to the flightline will do

allows you to literally dial up any of 50
aircraft channels between 72 and 73 MHz.

nothing. I like that safety feature very
much!
Optic System Choices: Hitec offers five
system versions of the Optic 6. The basic
aircraft system (featured here) is catalog
item 158721. With the Supreme PPM (FM)
receiver, four HS-325HB servos, a switch
harness, full Ni-Cd batteries and charger, an
aileron extension cable, a frequency flag set,
and an instruction manual, it has a street
price of $209.99.
The transmitter alone, with the Spectra
Synthesized RF Module, transmitter Ni-Cd
batteries, and charger has a street price of
$179.99. That is without receiver and
servos.
If you go to www.hitecrcd.com/Radios/
OPTIC.htm, you can see all of the system
options, which will help you when making
your purchase. If you click at the top of the
page on “Manual (PDF),” you will find a
reproduction of the entire 60-page operating
manual. Since the detailed control features
are available there, I won’t get into every
menu item here.
When you purchase a standard Optic
system, the transmitter is supplied with one
RF module of your choice of frequency.
You can purchase separately and substitute
the Spectra synthesized module later, or you
can obtain the transmitter with the Spectra
from the start. All 50 channels are available
on the aircraft frequencies from 72 to 73
MHz. Six-meter frequencies are unavailable
for HAM fliers.
Comments: As do most modern RC
transmitters, the Optic employs digital trim
on the four primary flight channel functions
(aileron, elevator, throttle, and rudder).
Since digital trim is activated by pushbutton
switches, the amount of trim being
employed can’t be determined by visually
looking at a trim lever (as it is on older
transmitters).
When you first power up the Optic’s
transmitter, the model name appears
momentarily, and then the normal display
appears. If you press either “EDIT” button,
you will almost immediately get to “TRIM.”
When the power is first turned on, the first
trim position shown is CH 1 (aileron). If
you haven’t set any trim, it will indicate 0%.
Each time you move the aileron trim lever
left or right, you will add trim 1% at a time.
Applying right aileron trim will cause
the number to go positive, such as +1%,
+2%, etc. Applying the opposite, or left,
trim will cause the number to go negative,
such as +1%, 0%, -1%, -2%, etc.
With the normal display in view,
anytime you press either EDIT button, you
will quickly get to the TRIM position
display. To look at other trim positions such
as elevator and rudder, you must press that
particular trim button. When you do so you
have added 1% elevator trim, and the
previously set elevator trim plus 1% will
show on the screen. After determining the
elevator trim position, you must return it to
1% to get back to your actual trim setting.
It is confusing to describe but easy when
put to use. The only thing you must realize
is that just one trim-function percentage can
be displayed at a time.
The Eclipse transmitter has a separate
dual rate/exponential (expo) rate switch for
aileron, elevator, and rudder (three
switches). On the Optic the elevator and
rudder are combined on one switch (so there
are only two dual rate/expo switches).
When using the Spectra Synthesized RF
Module, you must physically remove the
module and rotate two dials to obtain any
one of the 50 channels of your choice.
The Optic transmitter actually has three
timer functions, one of which is an elapsed
timer that appears on the right side of the
normal display. You are advised to set it to
zero after each battery charging. Then the
timer counts every time you turn on the
transmitter power. This will give you an
idea of cumulative operating time on a
single charge.
The other two timer functions allow you
to set a timed period of one to 60 minutes.
Both of these timer positions will then count
down to zero and sound an alarm (of your
choice).
The Optic 6 system is certainly easy to use.
The menu system takes little skill to
understand and operate. As a beginner,
you can only activate the special controls
you need. I like to see a beginner using
endpoint adjustment so that control throws
(travel) can be tailored to the new pilot’s
skill level. Having to do this using
mechanical adjustments can prove to be
tedious.
I’m also a big fan of expo rate control
since it will allow you to desensitize the
control feel around the neutral position.
Many airplanes “dancing around” in the
sky, with newcomers at the controls, have
been considerably smoothed out using
expo rate control.
I like the Spectra module since you can
easily change frequencies. Although you
must change the crystal at the receiver end
to match your Spectra, it can still be a
bonus when flying at a crowded club field.

systems are extremely attractive. Refer
