Activating Flaperons
Creating aileron differential
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:
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.
