brushless gimbal

this is my first brushless gimbal for a mobius camera.
the motors and the controller are from rctimer:
- 2804-100T brushless gimbal motor
- 2-axis brushless gimbal controller & imu v1.0
additional parts are:
- anti-vibration rubber balls from rctimer
- ball bearing 8x4x3 mm
- bolt m4 x 10 mm
- nut m4
the controller software is from here:
http://sourceforge.net/projects/brushless-gimbal-brugi/
here are a few movies with the gimbal in action.

update:
- arm2_final_v2 is an updated version, that adds a bit more space for the sensor module unter the camera.
- arm1_final_v2 is an updated version, with less imbalance on the roll axis, in case the camera is attached to the frame without additional weight from alpha gel pads.
- arm3_final_v2 added hole for zip tie (idea by marhar).
