Airplane Model Function Descriptions
subtrims are large values, the servo's full range of travel may
be restricted.
Setting Subtrims
1. Use the Edit Up Down keys to call up the STRM window.
2. Press the Cursor Right or Left key until the small arrow is
above the channel you wish to adjust (the figure shows
subtrim adjustment for CH1).
3. Adjust the neutral position using the Data +Increase or
-Decrease keys. You may adjust between -100% and
+100%. If you want to reset the value back to zero, press
the Active/Inhibit (Clear) key.
4. Repeat steps 2 and 3 for each channel to be adjusted in turn.
5. Return to the regular operating mode by pressing the two
Edit Up Down keys simultaneously.

REV - Servo Reversing

The servo reverse function may be used when you need to
change the direction that a servo responds to a control stick
motion. When you use this function, BE SURE THAT YOUR
CONTROL IS MOVING THE CORRECT DIRECTION. If you
are using any preprogrammed mixers such as flaperon, be
sure to set correct travels in the REV menu setting up the
preprogrammed function.
Reversing Servos
1. Get to the REV screen with the Edit Up Down keys.
2. Use the Data +Increase or -Decrease key to select the
channel you wish to reverse. The active channel number
will flash.
3. Toggle between normal (N) and reverse (R) with the Active/
Inhibit (Clear) key. The arrow above the number indicates
normal travel, while the arrow below indicates reversed
travel (the figure shows all channels normal, none reversed).
4. Repeat this procedure for each channel needing to be
reversed.
5. Return to the regular operating mode by pressing the two
Edit Up Down keys simultaneously.

T.CUT - Throttle Cut (Engine Kill) Function

The Throttle Cut function provides you an easy way to stop the
engine by simply pressing a button with the throttle stick at idle,
which commands the throttle servo to move a prescribed
amount. The throttle servo moves to the selected cut position
when the Cut button is pressed and the throttle stick is below
50%. Above 50% throttle, the cut button has no effect.
The activation direction may be chosen by the owner.
Setting up the Throttle Cut function
1. Get to the T.CUT screen with the Edit Up Down keys.
2. Place the throtle stick at its idle position (towards bottom of
transmitter). Use the Data -Decrease key to select the
amount of motion of the throttle servo you wish - normally
you want to completely close the carburetor, but be careful
not to choose too much travel that might stall the servo. You
may see the servo move when you press the Active/Inhibit
(Clear) button. A maximum of 50% may be chosen, but
only use the amount you need to fully close the carburetor
without stalling the servo.
3. Return to the regular operating mode by pressing the two
Edit Up Down keys simultaneously.
Note: the throttle servo will be disabled for a 2-3 second period after
the throttle cut button is pressed.
Note: The throttle cut function does not operate if Switch 01 controls
the throttle (see below).

STCK - Throttle Location

Your Optic system has a unique feature that allows you to
choose whether the throttle control plugged into channel 3 is
activated by the throttle stick or by Switch SW01(the switch
labeled "Elev Rudd D/R" on the top left of the front of the
transmitter). If you are flying an electric-powered model or
some other model that only needs the throttle to be on or off,
you can use this function.
Setting the Throttle Location
1. Use the Edit Up Down arrow keys to select the STCK window.
The window will either display the STCK display, indicating
the throttle stick controls channel 3, or the SW01 display,
indicating the switch controls it.
