Probably the smallest arducopter frame?

A long long time since I published last time, I'm drawing something fun and I thought you would like to see it!
It is a small frame all cnc machined from delrin sheet for 5" propellers. It seems a crazy project but i have a friend flying this kind of multicopters and it is really fun!

It is not originally thought for Arducopter but I recently purchased some Ardupilot 2.6 and i am seriously thinking to install one of them here.

Dimensions (center to center)
right to left = 165mm
front to back = 145mm
HD camera: Mobius
