Updated version here http://www.thingiverse.com/thing:734758

My mate Brian designed these as a curved legs that wont dig in when landing.
Make great carpark racing legs as you can skid on them.
Very resilient and very strong.
2 Versions one for small quads and the Alien size for larger 450 size to give more room underneath.
