I'm really amazed by this. It's really a simple thing. Get dressed and go. At first I thought well the drone comes with a gimbal lock, why would I need another to hold it in place? 1. It actually takes practice to turn on and off the original gimbal lock.2. It's much easier to use than trying to line up the original hanger lock.3. It's one less step as you install the cover at the same time as locking the gimbal instead of removing the cover, then removing the lock and putting the cover back on the drone.
