Just a word of caution if you're shipping your MP or if it will be handled by someone other than you. The gimbal lock and dome do not have a positive locking mechanism. They will pop off if the MP experiences enough downward force. The gimbal and mounting plate have enough play, and the vibration-reducing rubber bands have enough stretch in them to allow the entire camera assembly to move downward with enough mass to simply knock both clamp and dome off.
Either secure the dome to the airframe with tape, rubber bands, or Velcro straps before shipping, or make sure there is no space between the bottom of your case an the bottom of the dome. If the dome is resting on padding in the case, you'll be fine. But without some extra support, you'll find the clamp and dome off the MP, and the camera free balling the entire ride.
