Setting up a V-Tail
1) Activate the program by pushing down both DATA buttons
simultaneously-the screen will change from "Inh" to a % value.
2) With your model turned on, check your servo travel
directions-both rudder and elevator channels-to be sure they
are correct. Go to the S REV screen if necessary to make the
correction.
3) For a basic V-tail setup, you can leave all the values at 100%
so the "ruddervators" will move as both elevators and rudders.
4) If you wish to a rudder control to the aileron stick movement,
refer to the Aileron-Rudder mix on page 26. Use a small
percentage of mix for coordinated turns, or set it up at 100%
mix if your plane does not have ailerons and you wish to fly
it with the right stick.
FLPN (Flaperon)
V.TAL (V-Tail)
Setting up flaperons
1) Activate the program by pushing both DATA buttons-the
"Inh" symbol changes to the default 100% value. With your
model turned on, test the ailerons by moving the joystick to
the right and to the left: To the right, the right-hand aileron
should go up while the left-hand aileron goes down.
If this isn't happening, go to the S REV screen and reverse
the offending aileron.
2) Now check the travel volume: If the servos are stalling at
their maximum throw, turn down the value in the EPA screen
(or move the pushrod further up on the aileron horn to
physically reduce the throw).
Create aileron differential
Now let's create some aileron differential so that the ailerons
move about twice as much upward than downward.
Notice that the "MAS" (master) symbol is blinking along with
channel 1 and the % sign. This means that we can change the
travel value of the right-hand aileron (the master servo).
Also notice that L/U is showing, meaning the value will change
only for left-stick throw.
1) Reduce the downward movement to 50% by pushing down
the left-hand DATA button. Now move the stick to the right
and you will see R/D appear along with the default 100%
throw value.
Now we have differential-each aileron should be moving
downward about half the amount it moves upward.
You will likely have to adjust these values once you fly the
plane and observe the yaw of the fuselage as you roll the
aircraft:
2) To create similar differential on the left hand servo
(the slave) push down the right-hand CURSOR button
once-now the "1" and the "SLV" symbols will be blinking.
This time leave the L/U stick position at 100%, then move
the stick to the right to light up R/D and decrease the
downward travel value to 50% with the left-hand -DATA
button.
This is another built-in mixing program available in the Optic
Sport 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.
