IMPORTANT NOTE:
It is possible due to the particular configuration of your servos that servo reverse won't fix the
problem-you may get the ailerons working properly but not the elevator response on both servos.
Don't worry: You can fix this problem in the elevon programming by changing one of the servo travel
volumes to a negative value.
2) Now set the amount (and direction if necessary as noted above) of each servo-both as ailerons and
as elevators.
Because flying wings are extraordinarily pitch sensitive (because the elevator control surface is so
close to the airframe's center of gravity), you generally need the elevator travel to be much less than
that of the ailerons.
4) When you fly the model, if you find that this 40% reduction isn't enough to take out "pitchiness",
land and further reduce the travel volume.
To tone down the roll response, you can reduce the endpoints of the aileron travel or set up ATV on
CH 1 as described in the setup above.
V.TAL (V-Tail)
This is another built-in mixing program available in the Optic 5 that mixes the rudder and elevator
servos for controlling V-tailed aircraft.
Similar to elevon programming, the two surfaces can move up and down together (for elevator
control) or opposite (for rudder control in this case).
Note: When you select V.TAL, the ELVN program is rendered unavailable.
Setting up a V-Tail
1) Activate the function by pushing the pre-programmed switch to the right.
2) With your model turned on, check your servo travel directions-both rudder and elevator channels-to
be sure they are correct. Use the REV switch if necessary to make the correction.
CUT (Engine Cut Function)
Cut (Engine Cut) Function allows a throttle servo to max out the travel value (you can also choose the
direction by Servo Reverse Function) so that you can immediately cut off the motor when the engine
is below half throttle with a push of the "Eng Cut" button located on the upper right-hand corner of the
transmitter case.
Setting the Engine Cut Function
Press and hold the Cut switch for approximately three seconds to activate Throttle (Engine) Cut
function. The servo will travel more from its lowest (idling) throttle position toward to its End Point by
10%.
Note: Watch the servo movement on your model carefully:
You don't want to overdo the travel value or you'll stall the servo (you'll probably hear it buzzing if it’s
stalled-which creates a drain on the on-board battery and a potential over-heating problem for the
servo).
Setting the Gear (Retractor Gear) Control Function
The same button is used to cut the engine or control the landing gears (Up-locked/Down and Locked).
Use an Y-Cable to connect your retract servos to your receiver’s CH5 then make sure they are
properly operate. Push the Cut/Gear button once shortly to Up-locked or down and locked the
retractable landing gears.
