S. REV (Servo Reverse)
S. REV (Servo Reverse)
When you first turn on your model, you will immediately see whether all the control surfaces are moving in the correct direction when you
wiggle the controls.
If any are moving in reverse, you can come to this screen to reverse the throw of the offending servo.
Normal Reversed
Reversing a Servo
Let's say your elevator is going down when you pull back on the joystick, that is definitely not going to be a good situation when you go to fly
your plane! To reverse the elevator servo, come to the switch in front of the radio’s front panel. You'll notice that the symbol NOR and REV,
move the switch either NOR or REV to make the servo operate in the proper direction.
ELVN (Elevon mix)
Setting Up Elevons
If you are setting up a tail-less delta or flying wing aircraft, you can use this program to activate the pre-programmed elevon mix that mixes
the output on the CH 1 aileron and CH 2 elevator servo channels. As you will notice in the servo connection chart, you plug one aileron servo
in the receiver's channel 1 slot and the other aileron servo into channel 2-the slot that usually feeds the elevator.
This is necessary because on these wing types, the ailerons must double as elevators.
ELVN (Elevon Mix)
1) Activate the elevon function by pushing the pre-programmed switch to the left. Now check your model to see what happens when you move
the right-hand joystick side to-side. The ailerons should go up and down appropriately.
Move the joystick forward and back to see if the ailerons both respond correctly as elevators.
If necessary, use the REV function to reverse an offending servo.
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.
3) 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 set-up above.

NOTE:
When you activate ELVN, note that the V-tail mixing is rendered unavailable by the radio.
When you change the function of ELVN to V.TAIL or V.TAIL to ELVN,
Please TURN OFF THE TRANSMITTER FIRST and then change the function.
If you change the ELVN and V-TAIL functions when the transmitter is ON, nothing will be changed.
