QAV210 Mobius mount

Remix of ulflindestrom mount, adding an optional antenna mount, straight design (round was nice but not strong enough), optional hole for the board camera..

Version 3

It suits my setup, where I put the mount on spacers on top of the frame so I can put the receiver under and the antenna from the bottom into the mount tubes.

Version 4

New version so we don't need spacers, the receiver goes in the mobius mount, there are holes to let the cable go under. It allows the battery to be at the front and thus more centered CG
