Fenix

5" props 233mm quadcopter. I have laminated the bottom plate for better strength ratio. Flying weight without the battery 310g.

Designed for 18xx DYS motors and DYS20A regulators, you can fit Mattek distribution board and Naze32 on top, fits regular 200mW 5,8GHz Rx.

I have used carbon 3x15mm for the arms wich gives very tight fit.

Camera holder is fixed design from http://www.thingiverse.com/thing:984728
