Mini brushed quad copter.

thingiverse

I designed this project with the goal of mastering how to pilot these aircraft from the comfort of my own home. It's slightly on the heavy side at just under sixty grams, weighing in with a four hundred milliamp one-cell lithium polymer battery. However, with the propeller shield in place, it can withstand some impressive collisions and crashes, making it actually quite resilient. I designed it to print as much as possible in the X-Y plane for maximum strength. Parts list: Four 8.5 millimeter brushed motors (two clockwise, two counterclockwise) Four 55 millimeter props (two clockwise, two counterclockwise) One HappyModel SP Racing F3 EVO Brushed Flight Controller One Flysky FS-A8S receiver One one-cell three point seven volt lithium polymer battery One AFHDS two A capable remote control transmitter (if you want to use the above receiver)
