This is a DX7 and am using a 4 ch receiver built into the model already that I'd like to not change.
Currently I'm using the flap switch to input elevon offset for glide and boost setting. By mixing elevator to elevator with a negative % and mapping that to the flap switch as well, I can get reversed movement on the elevons on my boost position. However due to the mix it doesn't give me full deflection on that setting but it might be ok since that will be at higher speed and throw required won't be as much.
It's not the offset I need, i can do that, it's just the direction change mapped to a switch setting, since it has to change for a different flight mode.
Basically, when on the stack in boost mode, elevons are neutral and direction is reversed on pitch only.
In glide after separation, there is up trim on the elevons and direction is normal on both pitch and aileron.
I talked to one of the spektrum folks, they though on a dx9 it might be possible.

Might try a retract to elevator mix and program in an offset. I did something similar about 12 years ago with a Zagi 400. I had a powered mode and a glide mode. What radio are you using? I'm fairly good with most of the Futaba radios.
