Recently, I became interested in building small quadcopters for recreational purposes. In particular, first-person-view (FPV) racing drones.

It all started when I built my first drone. It was a 5” 4S quadcopter, able to carry a GoPro-like camera with a 3D-printed mount, and with low-latency video feed. If you are interested in getting into this hobby, I recommend the work by Oscar Liang and Joshua Bardwell. If you want to see what these custom-made quadcopters can do, check out the freestyle videos by Mr Steele and cinematic footage by Danny Mcgee and Johnny FPV.

Following the construction of the 5”, I became more interested in the “toothpick” class. In particular, those in the ~100g range, 2.5”-3” with 2S/3S input. These quadcopters are safer, allow indoor flying and are less of a disturbance in parks. With a proper camera and flight parameters, these can be as fun to fly as the 5”. This class was pioneered by KababFPV, and they are on the rise.
