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)

Comparing Precision of Autopilots for Survey Missions - Pixhawk with ArduCopter firmware

Posted by Kristaps Brass on June 22, 2017 at 7:00am 3 Comments


We have reached the long-awaited episode in our autopilot precision series in which we finally test Pixhawk. All drones are tested by flying them on a simple photogrammetry route created in UgCS mission planning software. In this video Pixhawk was mounted on 3DR IRIS platform, the same…


Drone Pilots Are Buying Russian Software to Hack Their Way Past DJI's No Fly Zones

Posted by CrashingDutchman on June 22, 2017 at 4:30am 1 Comment

Should drone owners be able to fly their drones wherever and however they want to? This is the question increasingly asked by the consumer drone community as drone giant DJI tightens flying restrictions on its customers.

This was the…

Getting down to target weight has been challenging.

This version is lighter, stronger, and stiffer than its predecessors. Only airtime and hard landings will show if its good enough.

I'm printing in PLA with 60% infill, 0.2mm layers and slow print speeds which seems to give the strongest parts.

I'll post photos when its…


Becoming a Land Surveyor-in-Training in three easy steps: How to actually make drone data valuable

Posted by Daniel McKinnon on June 21, 2017 at 7:30am 1 Comment

I recently wrote a little post designed to help those coming from a drone background pass the Fundamentals of Surveying exam, which I believe is an essential step to actually getting value out of drone data. Let me know what you think. Agree?…


How do modern open source autopilots compare to aerospace-grade IMUs?

Posted by Chris Anderson on June 20, 2017 at 10:21am 21 Comments

I noticed that Digikey is now selling Honeywell's newest aerospace-grade IMUs, which cost $1,328 each (note that's just for the IMU; it's not…


Aeromapper Talon demonstrates BVLOS capabilities by flying 30Km away from operators

Posted by Mauricio on June 20, 2017 at 9:01am 1 Comment

This time an Aeromapper Talon flew a mission autonomously to a target located 30km away from the operators, while maintaining at all times a strong communications and control link. This demonstrates the great potential for Beyond Visual Line of Sight operations for applications such as power line…


Phantom 4 vs dji Spark

Posted by Jared Reabow on June 20, 2017 at 12:24am 3 Comments

Just a comparison video for the benefit of anyone curious.

on a side note, it is strange that DJI has decided to make you connect to the controller via wifi (and has decided to use a stunted mavic controller), i found that you could connect via cable to the dji application via USB because my wifi…


3 difference flight controller types of flying style

Posted by Jack on June 19, 2017 at 7:30am 5 Comments

quadcopter Flight controller Flight controllers tend to be aimed at different types of flying style: Cinema Flying, Sport Flying and Autonomous Flying. At the same time, there is a massive number of flight controller brands in the market, so it's hard to know which is best. Today I will give some perspective on that.

Intel cancels Edison, Joule boards

Posted by Chris Anderson on June 19, 2017 at 5:50am 14 Comments

It was well known that Edison was going to be discontinued this year, but Joule, which was just released, is a surprise. This is bad news for any autopilot board that uses Edison, such as Pixhawk 2.1, which will now have to move to another companion computer. (I'd suggest Raspberry Pi). From …
