This is a camera mount for mounting the PilotHD V2 to a ZMR250. It's angled at 15 degrees. The two arms in the front slide down the standoffs in the front of the quad. It will work with any quad that uses circular standoffs that are about 0.2" diameter spaced about 1.25" apart.There is plenty of clearance for removing and inserting the SD card and hitting the record button (although, you might have to modify your frame to get to it).
This replaces the heavy metal housing that the PilotHD V2 comes with but still uses the backplate. I mounted mine by just putting double sided tape under it and sliding it down the posts. I might use a zip tie over the arms for good measure just in case.
