I recently crashed my Phantom 2 when it hit a tree on the beach. I took it home and opened it up to blow out the sand. When I replaced the cover in the correct orientation (The decals were cut on the seam so it was easy to match them back up) the props are spinning backwards pushing the drone into the ground. I can't understand why, because the only connection interfered with was the GPS connection. I'd really like to get back in the air again. With your help I should be able to. thanks in advance.
