I calibrated the compas, I had this GPS, I did it 3 times because an error, at the 3rd time the compas was fine)
I didn’t tune the PID, I let all value to default
I armed the drone, then I didn’t move a lot the throttle, and then the drone flip at less than 1 meter high, I broke a propeller and lost a metal part to hold it on the motor
Thank you maciek252 for your help, for checking the geographical north I forgot to check if it was correct, I just check on qgroudcontrol the health of the compass (my bad).
“the motors react correctly to the sticks movements”: I did it at home, only the throttle, I saw the roll was inverted on the qgroundcontrol so I inverted it in the calibration at home.
Also I was in Stabilize mode only
Re the buttons on MP’s motor test screen, to clarify, “Test motor A”, “Test motor B” “Test motor C”, “Test motor D” should be used to test the motors in a clockwise order. So “Test motor A” should spin the front right motor, “Test motor B” will spin the back right motor, “Test motor C” should spin the back left motor, Test motor D" should spin the front left motor.
Yes, it can be confusing but there are actually at least 11 different motor orderings for quad copters (only 6 are shown on the wiki) so we wanted a consistent check that was always the same regardless of which motor ordering is chosen.
