Tilt Rotor Servo range issue

ArduPlane VTOL Plane

Having issues with a tilt rotor in a qplane setup. When swapping from a Qhover or Qstabilize setup to a FBWA, i want the servo to rotate 90 degrees from vertical to forward. However, when I swap modes, the servo barely moves (~40deg), even with the minimum set to 800 and the max set to 2200. What is interesting, is that the larger this range is, the more it moves, however it does not go to the min or max i set. The range also increases as I increased the trim value. The 40deg max rotation is from a 800-2200 range, and trim at 2200. The actual output however is only 1897 and 2200. The servo is a DS3235, which is a continous rotation servo. All of my Q_tilt params are at default. Currently the servo is set to function TiltMotorFront. Please let me know what I can check!

I followed Tilt Rotor Setup Tips — Plane documentation setup steps exactly, the servo would barely rotate 2 degrees starting at 1300-1500-1700

It’s not unusual to have to set abnormally wide ranges on VTOL tilt servos. I’m looking at one of mine and it’s ~900-2300. But I wonder if using a continuous rotation servo might be causing part of the problem.

Hi @Sachet_Patil

welcome to the forum. To get started, you should not start with the ‘Tilt Rotor Setup Tips’, but work through the ‘First Time Setup’ guide for the tilt rotors first:

If you still have questions after that, please post them here.
