CC3D Atom Nano / Micro Skyhunter mount

Violently rammed a cc3d mount into my nano skyhunter receiver plate. What a kludge! Thanks for your hard work though altermac.

Should work with ~16mm m3 screws, I'm using 18mm because that's what I had around. Go slow with a receiver mounted to it (or install the receiver afterwards). Even with a naked x4r I had a tight squeeze.

update 1: fixed fc holes to match original.
update 2: cleared usb area out so you can actually connect a usb cable.
