Quadcopters, FPV, open source and 3D printing. How much do these exciting technologies have in common? More than you might think. While it’s not yet possible to fabricate components like motors, sensors and electronics it’s entirely possible to 3D print parts like the frame, landing gear, and even propellers.

Punkkills has recently published his design for a truly impressive 105 brushed FPV quadcopter. Punkkills frame was inspired by the FireFlo V2 and the Alpine Drones Micro H. Goals were to keep it crash resistant and light weight. Frame measures ~105mm, weighs ~8g when printed in PLA, a full build weighs ~38g without the battery. It is designed around 8.5mm motors and the Micro Scisky, a Naze32 type flight controller. A really small camera and FPV TX module provide the first person flight experience.

FPV 105 Setup:

Punkkills recommended PID settings for Betaflight 2.4.1 will get you about 4 minutes of flight at insane speeds.
