2 aileron servos per wing? 4 servos total? Like a big giant scale 35% plane? You need a Matchbox.

Or one smaller sport plane with only 1 servo per side? Simple programming.

You need to enter the main men u on start up and tell it that you are using a FLAPERON wing.

Then you go into the FLAPS channel and set BOTH endpoints at ZERO.

You still have to use the FLAPS sub-trim menu to center that servo. But FLAPS TRAVEL must be set to ZERO.
