Scythe Motor cover for UDIRC 816 quad copter - protects your delicate wings

These are copied from user gsterley, but modified so that you would not need to take your original motor mounts off.. These just slide on over the existing motor mounts. They fit fairly snug, but are shaped so that they leave some air space to allow the motors to keep cool.
Update 8-4-2014 I decreased the mass of these slightly and cleaned up my rough curves, and have put mirror images on the same print. That way you can make one print in one color for the back and another print in another
