Flaperon programmation

Hello everyone,
I have a devo 12s with deviationtx 4.0.1 and a glider with 3 servos per wing (1 for aileron, 1 for flap and 1 for airbrake).
I have no idea how to process the programmation of Flaperon mode using banking on stick and camber position on the FMOD 3 positions button
Does anyone have a solution or a tuto to help me?
Apologize my bad english, but I'm french.
Thank you all.
As I 'm new on this forum, I hope i'm writing in the right category.
Have nice flights

Since it's fixed wing, you need to be using the advanced gui, not the standard one. Using those extra channels will require that in any case.

I wrote a tutorial on dealing with the advanced gui mixer programming that walks you through a relatively complicated setup for a quadcopter. It should at least get you started, thoug if you have really complex the interactions on the various flaps/brakes/etc. it won't get you all the way there: deviationtx.com/forum/how-to/3948-tutori...-a-model-config-file

Thank U MWM.
I 'll read this.

Once you have read the tutorial, you can look at this model file for the Lanyu ASW28 glider by Birdman
