Inverted elevator on flying wing tilt rotor

ArduPlane VTOL Plane
1

Hello,
this is my first post here as I’m just run into trouble while setting up my first VTOL with latest Plane 3.8.
It is a flying wing, so I’ve setup the control surfaces as Left and Right Elevon. Everything seems to be fine if I move the plane around in FBWA mode, the control surfaces moving in the right directions. But if I try to control them from my RC transmitter, I’m getting inverted movements on the elevons from elevator stick movements.
The only idea I have currently is to invert the stick movement in the transmitter calibration process. But I afraid, this could have side effects?

Thanks for any help in advance!

double check all your controls are acting in the correct direction as outlined in the TIP here

I already did this multiple times - but you are right:
In my case all green bars are moving in the same direction as the transmitter stick.
In opposite, the Wiki says:

The green bars should move in the same direction as the transmitter sticks (except for Pitch where the bars move opposite to stick movements - low values are forward, high values are back).

Thanks a lot!
