When I was testing my new sparky flight controller with the GPS yesterday, several kids are surround with the copter and me, I’m just like a freak. damn it.

很无奈，这眼镜不太适合我宽阔的脸颊，aio是没有这个问题的。
Dominator hd doesn’t fit my face.

With a 5v laser diode<taobao> , 90mah lipo beterry <taobao > (hmm,little expensive), a SMT-swich(from a damaged wifi router). I made this torch thing. Two black holes were made from “dupon pin” <taobao> for charging. Actually it’s a waterproof design.

easy to use
