"in my drone gimbal camera getting problem. gimbal motor over loaded"に関する回答The gimbal motor is overloading because something is blocking the movement of that arm or the camera. If the roll arm is bent even slightly the camera will hit the ribbon ledge and cause overloading. Send it to your nearest DJI repair facility.
"Little access door on one leg"に関する回答Be sure the landing gear isn't broken at the leg where the screw cover came off. Sounds like the leg may be bent a little which is causing the cover to not fit properly. It should snap in after inserting the prongs into the bottom of the opening (with the drone right side up - top of the opening if it's upside down).
