Cheerson CX-20/Quanum Nova Quadcopter landing gear/skids for Gimbal

Original version couldn't handle a gimbal - http://www.thingiverse.com/thing:761547

This version is designed to handle a camera gimbal under the quad. I'm not sure this is as strong as the first one, but we'll see. The crossbeam is optional, since some people may prefer the gear to flex a bit.
