This is very inconvenient to me every time connecting battery and arming the copter, the board is automatically leveling (calibrate sensor) . Could we disable it?
because it is hard to have a flat surface to lay the copter and level it.
Could we do it at home and bring it to field and fly?
BTW, my copter always bend forward, how could I fix it? I calibrated manually and still got problem,
Please let me know how to do with it.
"Auto leveling" is not what is taking place here. No need to disable- it is simply calibrating the gyros. You do not need to have your copter flat to power-up. If there is any drift in your flight it is most likely due to either vibration or a copter that was not level during the user-initiated leveling routine.
