Syma-X8C quadcopter gopro mount.

A camera mount for straight down gopro shots.

I used a foam scrunchy as a vibration damper - you choose whatever material you like.
I used silicone hairbands to hold it together.

I've posted the shoe is two sizes. The high profile one takes an M3 knurl nut while the low profile is just glued.

On board video from the test flight is here - https://www.youtube.com/watch?v=efYNgQyOugU
The protective lens I had on hand and I think it is this.
