ArduCopter 3DR Quadcopter

Quadcopters rely on computer stabilization to fly. They can be radio controlled, but with an onboard computer, why not let it fly itself? The community at DIY Drones developed the open source ArduPilot Mega (APM), an Arduino-based autopilot that lets you control multi-rotor (and other) aircraft autonomously, or via R/C. The ArduCopter 3DR Quad Kit […]

Medieval Battering Ram
