VTOL Transition problem

Hi everyone

We created a custom 4x tiltrotor VTOL, using the CruseAder Claire configuration on QGroundControl.
Everything is okay, except during transition: the first part of the transition works well, but when reaching the angle we set up, we need to considerably reduce throttle command to finish transition. After that, the reverse transition works well.

Any ideas to fix it ?

Thanks

It’s likely a (small) code change. Are you able to share flight data (logs and possibly video)?

Did you use air speed sensor?
If not, you should set FW_ARSP_MODE 1.
Reducing throttle means you on ground.

Thanks a lot !
Now everything is ok
