Quadcopter Hat Prop

I was trying to find a hat that told everyone I was a quadcopter (or drone) pilot, and was unable to find anything.  I came up with this clip on prop that you can add to any baseball cap.  If you put four on the cap, you have a quadcopter.  You can mix and match the colors as you will be ordering individual Hat Props.  I chose to use two whites up front and a red and green in the back.

When your Hat Prop arrives, it most likely will be free spinning.  If it isn't, it shoud be a simple matter of using gentle pressure in alternating directions to free it.  Take your time and don't press really hard because if you do that it is possible to break it.
