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

I'm new to all this--where do I start?                   Are amateur UAVs legal? (yes)

Building a sub-500 gram (< 1.1 pound) quadcopter

Posted by yannis on September 18, 2017 at 3:00pm 5 Comments

I wanted to build a lightweight quadcopter frame for some time, and I've eventually found time to do it. Hereby I summarize some aspects of the build that allowed me to save weight.

Note that this is a summary of the complete post in my blog.

I’ve chosen to build a very simple X frame for this build. The frame is made out…

The CHICOMMS Syndrone

I must preface this entry with the disclaimer that most of it is postulating on my part. It is meant as food for thought on possible motives for why a company would voluntarily launch a haphazardly designed and untested system that ultimately serves to limit their product viability. Another notable mention would be that I […]
