I wanted something other than what was out there already.
It hooks over the tabs for the gimbal mount in the upper fuselage and fits with minor tension between the lower rear gimbal rubber mounts.
Easy install: squeeze the sides, set in place, slide it back, release.
It wasn't designed to trap the gimbal: it's just a cover, but it does restrict gimbal movement when in place.
The text plate was done separately for easier overall printing.
