ADIF (Aileron Differential)
Activating Flaperons
Creating Aileron Differential
STCK (Throttle Stick or Switch)
If your glider uses an electric motor for self-launching, the GLID programming baseline thoughtfully allows you to retain throttle control even
if you opt to activate the CROW function on the left-hand joystick/throttle stick. To make this change in order to have a proportional CROW
function, follow these two steps:
1. Be sure MAS and "1" are blinking. Now, as you hold the stick
to the left, reduce the value with the -DATA button to 50%.
2. Use the Right CURSOR to get "SLV 1" blinking and then
reduce the travel value to 50% as you hold the stick to the
right. Now your ailerons are programmed with 50% differential.
This is the Main Function Menu screen (instead of FLPN in the ACRO baseline) where you can
activate the aileron servo plugged into channel 5 to create flaperons. It is also where you can create
aileron differential: Being able to adjust the ailerons so they can travel more in one direction
(usually about twice as much UP movement as DOWN) is an especially important quality for sailplanes
as differential reduces the "parasitic" drag due to a yawing fuselage and unnecessary aileron travel.
Using the right-hand EDIT button, scroll down to the ADIF screen and activate the differential
programming by pressing both DATA buttons.
The "MAS" and CH "1" should now be blinking and CH 5 "SLV" holding steady
(indicating the master servo is channel one and its slave is channel 5).
The default values for both left-hand stick throw (L/U) and right-hand stick (R/D) should be 100%.
Now, when the right wing's aileron moves up and down with the stick throw, the left-wing aileron
follows suit (but in the opposite direction).
If you activate the CROW function and/or the Elevator-to-Flap mix, both ailerons will move in
unison as Flaperons.
Note: You must activate this program to create flaperons before you can set up Elevator-to-Flap,
Camber, or Crow mixing functions.

Initial Menu Feature Review for GLID Programming
The following item is located in the Initial Menu as described on page 13 -15. We will review it here.
Select the Model type baseline: In the second menu screen, the programming baseline of
ACRO, GLID, or HELI will be blinking.
Since we are setting up a Sailplane, select GLID by scrolling to it with a CURSOR button.
Push down both DATA buttons simultaneously to tell the program to accept the choice-you should
hear the transmitter beep twice in acknowledgement.
Important Note: Do you have a "flying wing" glider?
In the GLID mode the ELVN program is rendered unavailable-if your glider is a flying wing, use the ACRO
mode to set it up.
Model Setup Main Menu Programming
STCK (Throttle Stick or Switch)
In the GLID programming baseline three new functions appear that are not available in the ACRO mode: A CROW function allows you to
program a descent control in which both ailerons move upward while the flaps move downward; an ADF function creates flaperons and
aileron differential and a STCK function moves the throttle of your glider's motor off the left-hand joystick and places it on the switch
SW-1 on the upper left-hand corner of the transmitter case (which frees up the joystick to proportionally control the "CROW" function.)
1. Go into the Main menu and scroll down to the STCK screen.
The default setting puts the throttle on the left-hand joystick.
2. To put the throttle on the switch SW-1, push down both DATA buttons simultaneously and watch as
the screen displays "SW 1". Now, when you move this switch toward you from "0" to "1", the motor
will come on with full power
At this point you should have selected GLID in the Initial Setup Menu as the baseline programming
for the model you wish to set-up. In the text that follows, we will review and explain the Model Setup
Menu items specific to the GLID Menu for setting up your glider.
For those GLID features common to ACRO, refer to their description within the ACRO section to set up
your model's basic functions (such as servo reverse and end point travel).
Now let's reduce the downward travel of each aileron to about half that of the upward travel
(a good starting point for setting up differential on a typical sailplane:
