As mereflyer has already mentioned, fabricate a "Remove Before Flight" ribbon and attach it to the gimbal cover... Since the Gimbal is probably the most delicate component of the Drone, I recommend you install it first and remove it last whenever you are handling the Drone (changing the battery, etc...) and especially if you are showing the Drone to someone. You would be surprised how many folk will "pluck" it to see it move. Finally, when you getting ready for a flight, remove it after you've opened the legs... Then, remove the cover, turn your Drone on, let do it's self test, then set the Drone down. When you have adequate satellites, lift off, 1 to 1.5 meters, just float there a moment, get the Return to Home updated, perform a few movements, up/down, left/right, yaw...Then, when you know the Drone is responding correctly, then Go Droning....
