Hey everyone!
My name is Gareth and im busy setting up a sky hunter for photogrammetry.
Plane is assembled and test flown. She flies like a dream in manual mode.
The skyhunter doesnt have a rudder, so there are only 3 servo outputs (left aileron, right aileron, elevator) and the esc.
When i setup the plane i joined both ailerons together to go to the 1 aileron channel. Is this correct?
I performed the calibration in QGC, all went fine, only to find that the control surfaces were reversed in manual and assisted mode.
Iv had a fair amount of experience with arducopter so Im not a total noob.
In order to invert the control surfaces i change the fc orientation in the software, i changed it to YAW_180.
This fixed the inversion problem but inverted the artificial horizon. When I pitch down the artificial horizon pitches up and same for roll. How do I fix this?
Now when I try assisted mode (seatbelt) it seems to work fine, it keeps level flight no problem.
When I switch into assisted mode (easy) the motor just dies and she falls like a brick.
When I switch into loiter or RTL, it throttles up to 100% and rolls almost 90%, while simultaneously diving.
Could someone shed some light on what im doing wrong?
For troubleshooting, I have attached my parameter file and the mavlink telemetry file :)

Thanks guys!!!
Your help is greatly appreciated!!!

Have you reversed the aileron channel in your TX but not in the Pixhawk firmware? You shouldn't need to adjust the board orientation if the servos move wrong only change the direction that the Pixhawk moves the servos. If you have told the board it is yawed 180 degrees it will also assume that pitch down = pitch up which probably explains the dive and throttle movement.
