Question for folks here. I somehow managed to drop my MM while in its DJI case case half way down a scottish hillside (don't ask) when i retrieved it, there weren't any scuffs or scratches on the drone itself. I'm wondering what all that jarring impact might have done to the gimbal? the drone seems to be operational and flies ok, except for an error message saying that one of the propellors is rotating too fast. i have checked the blade, and will replace it when i get home even though there doesn't seem to be any damage, I'm trying to figure out if there is any other damage i should be checking for? any input would be appreciated.
