==== 2015/06/11 ADDED NEW PROPELLER SIZES!! ===

As a new multi-rotor pilot who has gone through many broken props and lost screw caps, I wanted to create a better, more convenient prop adapter.

It needed to:
- Allow super quick prop changing.
- Require no tools
- Require no tightening, or human strength
- Will not break mid air (the way a prop saver does)
- Will not break before the prop breaks during crash

Designed to sit on top of a standard M5 Prop adapter. The base is locked down with a nut. (Lock tight can be used since this should not need to be removed often)

This is now close to a final version. I really would like your thoughts so that I can continue to improve the design.

I would like to invite my fellow pilots/printers to PTR (Print - Test - Report)
