Simple quadcopter frame

thingiverse

This is a straightforward quadcopter frame. The entire frame can weigh less than 80 grams (depending on infill density). You'll need four arms, one top part, and one bottom part. The frame supports propellers up to nine inches in diameter. My quad uses the following components: - Four 2208 1100 KV motors - A single 20A 4-in-1 ESC - A CCD3 controller with a DSM satellite receiver - A 2S Li-ion battery (I use two 18650 power tool cells, which weigh 90 grams) - Four 9x4.7 GemFan propellers - Four 20x3 screws and nuts The total weight of my quad is 395 grams. My quadcopter consumes a moderate amount of power, with a current draw of five amps at seven point four volts for hovering possible. With a sixty-gram payload (the power meter), I measured six amps. This means that with a two ampere-hour battery capacity, twenty-minute flight time is achievable, making it an ideal training vehicle for beginners. Update: A second version of the arm features a simple landing gear system.
