Vectored tailsitter flips backward

ArduPlane Plane 4.5
1

Hey,
I am working on a vectored tailsitter. The two tilt-rotor servos move only to the trim value (forward flight position) but not further (see picture). Therefore the plane is always flipping backwards when I slowly raise the throttle at liftoff.

Can someone point me to what I have configured wrong; download link of the bin file: SwissTransfer - Envoi sécurisé et gratuit de gros fichiers

Nobody any suggestion why my vectored motors only work down to the trim value when vertically?
Servo1-2 Elevrons
Servo3 Function: 75 min/tim/max: 920 1520 2120
Servo4 Function: 76 min/tim/max: 1020 1620 2220
Servo5-6 Motors with dshot600
If I run the tilt servos from a servo-tester they run from up90° to down90° but somehow the stabilization lets the servo only run from up90° to 0°…
thanks for any help from the vectored Dual-motor tailsitters pros :slight_smile:
