Quadplane Take-off abort


I have a VTOL (quadplane) and it is the second time that my drone stops climbing during take-off. Flight mode is Q_LOITER and when I reached 15m, impossible to go up so I had to land.

In the flashlog, I don’t have any error message and any information that could explain what happened.

Do you have an idea ?
