I have a DX8 transmitter set to normal wing setup - 1 servo for aileron and 1 for elevator.
My plane is a delta so of course when I move the stick to go up and down the right side moves, and left and right the left side moves.
I then check the box in Mission Planner for elevons but nothing changes - I still have the right control moving for pitch and the left control surface for roll. No sign of them working together.
My APM is a 2.6 with firmware 3.4.
How can I get them to work?
