This is designed to hold and mount the Fatshark 600tvl Camera that is supplied with some of their kits such as the Predator v2.
Its simple design allows secure mounting to a GoPro mount in either orientation. The cam slips into the flexible frame and snaps tight... it may not look it but it holds VERY well.
It is perfect for being hung under a craft such as a quadcoptor (pictures show a Phantom) but it can be sat on top of a craft too such as an FPV plane, wing, Bixler etc
Please note - This fitment was correct as of Oct 2013 - Fatshark are know for replacing components without warning so please check the model carefully.
