Hi I have just finished my first Arducopter and detected a strange behavior of my APM Board.
I have to reset it several times on the field (not connected over USB) before it is starting up correctly.
Sometimes it hangs during boot, sometimes the sensors are not working and other times it is not possible to arm the motors.
Have any of you ever heard of this issue, because I cannot say that this is a constant behavior.
Could this be a hardware issue (APM or IMU)?
