I am attempting an auto VTOL takeoff of a bicopter. When moved into takeoff mode, one tiltwing tilts back and one tilts forward. Additionally, the motors spin momentarily, then cutout (and sometimes one before the other). Attached is a link to a log where an attempt at a takeoff occurred. Any help would be greatly appreciated!

edit: Tiltwing servos are servo5 (left) and servo9 (right). Motors are servo2 (left) and servo1 (right)

Additionally, when in vtol takeoff (though strapped down w/o propellers), only the left tilt servo reacts to pitch changes. The right tilt servo maintains its forward position - very strange.
Realized the left tilt servo moves into its SERVOX_MIN position at takeoff. This servo is reversed.
edit: With a Q_TILT_YAW_ANGLE of 0, the right tilt servo moves to a position halfway between servo_min and servo_trim. As the angle is increased, the right tilt servo moves closer to servo_min.
Take a look I think we are having the same issue.
Hi Rolf and Dave,
I made a double check. V22 uses cyclic blade to control thrust because it is using engine. We don’t need that with electric motors because electric motor can accelerate and decelerate fast enough. You can check this video
Today I tried to do
On left/right Bicopter with Pixhawk6X + Ardupilot4.2.2
By Q_TILT_MASK=1(only Left Motor is tiltable)
Q_TILT_TYPE=0(this is according to what Peter Hall
@iampete told me
Q_TRANSITITION_MS=1(turn off Right Motor imm…
