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](http://www.hobbyking.com/hobbyking/store/__64147__Dart_400_FPV_Quad_Copter_With_Power_Distribution_Clean_and_Dirty_and_LED_Illumination.html "Dart 400, From Hobbyking") 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!
