Hi there,
i have a 2.5 kg Thrust vectoring Tailsitter system with 16 inch APC props. the system was tested in Qloiter mode when performing a quicktune, and it was holding altitude and position
but in the recent flight the system took off in QStabilize without any issues, but the minute i switched to Qloiter, the system shot up to almost 100m after which i switched to FBWA mode.
in FBWA mode it nose dived into the ground and is totalled
2 issues in the flight
- Why did it shoot up in Qloiter mode
- Why did it nose dive into the ground in FBWA
for Question no 2, the control surface area was reduced by almost 50% for aesthetics and testing, and PID values were old ones, the idea was to perform a Autotune in Fixed wing mode.
attached is the link to the .bin file.
Requesting to please go through it and help me understand why the failures happened.
