I wanted to build a small quadrotor that I could safely fly around the yard when at home. Since I had just assembled my own CNC machine I thought it might be time to try building a mini quad.
I designed a very simple and versatile frame, cut out the pieces from 1.5 mm natural acetal, prepared the arms, and gathered all the hardware. Since the build is centred around 5×3 propellers, I opted for 110 mm arms, allowing a motor-to-motor distance of 240 mm. The arms are basswood that has been prepared and coloured with a black dye.
The total weight of the frame is 46.5 g.
The all up weight with battery is 267 g and it hovers at about 60% throttle.
