Summary

I have recently built a ZMR250 Quad-Copter using a Sony CCD (PZ0420) board camera and felt that it was a little exposed at the front in event of a nose in crash.

So I designed a 'guard' which slips over the 2 front pilars and adds protection, without getting in the way of the view of the camera.

Simply print 2 of these, and mount them as shown in the photo.
