Chris Anderson, of DIY Drones, sends us word that ArduPilot 2.0 Beta has been released. It has built-in stabilization, making it a full-functional autopilot — no third-party stabilization unit required. It uses the same $25 ArduPilot hardware, so all existing owners should be able to upgrade without issue. This is pretty amazing — the functionality of a >$1,000 autopilot for less than $100! Go DIY Drones!
