Now, flip over the drone, and orient it with the camera facing you. You should remove the camera/gimbal cover at this point, but its probably a good idea to leave the gimbal brace in place.
Remove the four closest screws circled in red. The ones closest to the front are 5.8mm long, with a 2mm diameter, while the ones closer to the rear of the drone are 4.8mm long, with a 1.5mm diameter. Be careful not to confuse these screws when reassembling the drone.
