120mm Quadcopter frame

I made my own quadcopter frame. It is designed to fit a f3 evo brushed flight controller in rails, 8520 motors and a receiver under the flight controller. It is also possible to mount an AIO fpv cam on the front(eachine dvr03/eachine tx03). I also made a small lid for it.

Parts I used:
