These were designed around the hyperlite tooth fairy frame (arm size doesnt matter). It’s a camera mount with integrated battery pad for top mounted setups. The top pad keeps your battery safe from the protruding screws that hold the frame together.
The camera mount has 2 locations. The front hole pattern lets you rip around on crazy fpv angles. The back hole pattern offers more protection but less angle due to camera / FC stack proximity.
We sell these with the printed cross-member supports. After using them and putting them through some crashes, we actually like to cut that out and slap on a small piece of Velcro. The Velcro keeps the batteries super secure, and the TPU spacer keeps the batteries safe from your frame screws. We’ll ship them fully printed, but we wont get mad at you if you decide to cut them out for some 3rd party Velcro.
