Gopro Cage for Emax 300 FPV Quadrocopter

This is a frame for mounting a Gopro (Hero3/3+) into an EMAX 300 foldable quadrocopter (see 1st photo for how to mount).
You have to replace two metal spacers of the copter with this thing, use M3 nuts and slide them into the holes. You have to drill a suitable hole in the lower carbon frame piece (see 3rd photo). The camera can still be operated while mounted.

I used this to perform vertical shots with a very small and portable drone by putting the Gopro into time lapse mode before starting
