Today I fly inside (outside was to cold). I was wonder what will happen when there is no chence for GPS fix.
I get all necessary precautions and switch from manual mode to Alt/Pos hold.
In reaction to the change mode, got a huge acceleration engine, copter nearly crashed into the ceiling.
If you need flyt inside building, only manual mode for now is possible, it is not good.
I hope in the future to separate Alt hold from Position hold.
Do You think its usefull or unusefull option (was there any discussion about that)?
