Hi, could someone please help me with this problem. My mini constantly does 90 degree spin to the right side as if 1 of the motors momentarily stops for a split second. This happens usually 3times consecutive and then I slow down to a very low speed to bring it home safely. Is it possible that the left front motor malfunctions for a split second and causes this 90 degree spin. No message pops up on my fly app to show a possible reason for this spin in mid flight.
