Failed Transition

Hello guys I asked that question on another page but I want to know more than Q_LOIT_SPEED any chance to help me?

I’ve tried a maiden fixed-wing flight from Qloiter through the FBWA but failed three times during the transition. The first one did not reach to transition and I stopped it manually. On the second try plane started to rotate in yaw uncontrollably and the final, last try made weird moves when I turned back to Qloiter probably because of the batteries moved inside of the plane, and crashed to the ground. I am adding logs and videos of the transitions. Can you help to diagnose the problem?

My t1 ranger vtol always fails to transition and I had to select to transition to fixed Wing anyway with just a warning… But besides it saying transition failed it turns into fixed wing and flies just fine

Oh, lucky. I am afraid of failing again. Btw what do you mean by selecting a fixed wing didnt we just change the flight mode to one of the fixed wing modes?
