Mobius Cam Gimbal Ver. 2.0

This I think, is a far superior design to my earlier offering. Just as sturdy, certainly more compact, and just three parts to make and it's a bit lighter. easily configurable for mounting on the aircraft top-side, bottom side, or horizontally. Use metal gear servos and it should be quite a reliable gimbal. In my build I used a HiTec HS81 and a Turnigy 620DMG+HS (just what I had laying around the shop).
Two base-plate options are provided here. This mount with the larger of the two base-plates and metal-gear servos weighs-in at 119g (less camera).
