Welcome to DIY Drones!

Welcome to the largest community for amateur Unmanned Aerial Vehicles! Use the tabs and drop-down menus above to navigate the site.

This community is the birthplace of ArduPilot, the world's first universal autopilot platform (planes, multicopters of all sorts and ground rovers). Today the Pixhawk autopilot runs a variety of powerful free and open UAV software systems, including:

  • PX4, a pro-quality copter, plane, rover and VTOL software stack from the Dronecode Foundation
  • ArduCopter, a fully-autonomous multicopter and heli UAV system
  • ArduPlane, a pro-level UAV system for planes of all types
  • ArduRover, a fully-autonomous ground-based vehicle system
