Legs for Multi-rotor

I build various multi-rotors; I've been building various H-Quads for a while and have been watching out for "wide" legs that are:

• Light weight (~20G printed in PLA)
• reusable (they bounce!)
• tough (they come off in crashes, but I have not reprinted them in months!)
• easy to print (these do take a bit of care, due to the open spans!)

I've been using these legs on a modified Dart 400 flipped upside down swinging 10" props. Lots of room for a Gopro in the front, and a blast to boot around with!

NOTE: This does take some care to print; see the instructions!
