BDX Motor Guards

A few iterations of arm/motor guards for the Red20RC BDX racer. Started out with outer lines matching the arm. Wanted more motor protection and less weight under the arm. Second revision was a bit heavy, so reduced the bottom further and slimmed down the motor protection. BDX_Skid4-best is the version that I use on mine, which weighs in just under 6 grams printed at 15% infill, 3 outer layers, 4 top/bottom.

Print in TPU to allow for some give in hard crashes. Note these dont stick down past the center of the quad, as I wanted to keep them light, but ill try to post a center skid soon, too!
