I know that this is a very recurrent question and I apologise for any redundancy.
I assembled recently a Tarot T960 frame, T-Motor MT3514 400 (X6), T-Motor ESC 40a (X6), emax 6 axis power board, Pixhawk, 3DR GPS module(X2), 3DR telemetry radio, RC Taranis X9E and receiver X6R.
I managed to get it airborne during first trial, but unfortunately, one of my props was not tight enough and came off in the middle of a flight. The hexa landed with the arm missing the prop, which obviously broke. It also inutilise one of the land gear arms.
After getting the spares and assembly the hexa again, it doesn't want to fly. Instead, it flips as the video shows.
Any ideas on what could be wrong?
Yes, props are all spinning correctly, motors seem to have the same speed, no weird noises, frame set to X shape, etc.
