I began having reservations about my P4's stock gimbal lock when I noticed how easy it was to place it on with the camera arm either forward or rearward of where it wanted to sit naturally, thereby placing undo stress on the gimbal buffers (I believe they are called). Anyway, I was getting ready to mark my lower horizontal legs where the gimbal lock clips on with a Sharpie to make it easier to line up the lock's arms correctly each time, and then, I suddenly noticed something. If you turn the P4 over, DJI has already placed little lines in the landing gear's rubber strips to indicate where the locking clips need to be. I have never heard or read about this, but there they were. Genius!!
