Retractable landing gear and 3 axis gimbal for hexcopter/quadcopter with SJ4000 cam

Retractable landing gear and 3 axis gimbal for hexcopter/quadcopter.
used generic retract gear and a sailwinch servo along with a generic 2 axis gimbal.

have used some of the source parts as is, some are modified and some are of my own design. holes in the top plate are designed to fit to rails of 65mm centeres.
have included all the parts here.

Sailwinch servo is a SW4805-1.5PA Kingmax servo - from ebay.
