Welcome to DIY Drones!
This is the home for everything about amateur Unmanned Aerial Vehicles (UAVs). Use the tabs and drop-down menus above to navigate the site. (About us/Site rules)
This community created the Arduino-based ArduPilot, the world's first universal autopilot (planes, multicopters of all sorts and ground rovers). The APM 2.5 autopilot hardware runs a variety of powerful free UAV software systems, including:
- ArduPlane, a pro-level UAV system for planes of all types
- ArduCopter, a fully-autonomous multicopter and heli UAV system
- ArduRover, a fully-autonomous ground-based vehicle system
I'm new to all this--where do I start? Are amateur UAVs legal? (yes)

Man whose RC drone was shot down over Turkey protest returns to the skies

Many of you might be aware of the situation in Turkey, where protests have been going on for longer than two weeks. Some of you on DIYDrones might also be aware that a man was flying a small RC drone above these protests, that is, until his aircraft was shot down by riot police.

My dad likes remote control cars. My brothers like remote control cars. I like them too. As a family, we grew up playing with train sets laid out on the family dinner table. As kids we also used to enjoy playing with a “Thunderloop Thriller AFX Slotcar Set” and making things out of Lego. The things that typical boys enjoyed playing with.
So where do I begin with this flying journey? How about this last Christmas. It was the year of… strangely enough remote control…

PSNI on G8 drones: ‘They actually look like big model aircraft’
THE POLICE SERVICE of Northern Ireland (PSNI) have revealed details about the unmanned aerial vehicles or drones they will be using during the G8 summit, which gets under way in Fermanagh tomorrow. As part of an unprecedented security operation at the Lough Erne golf resort near Enniskillen, the PSNI will be operating three of the unmanned aircraft over the next two days to give them an “eye in the sky” view of their operation. The drones will be used primarily for surveillance purposes during the summit and will deliver high quality images to police commanders. The PSNI will have 8,000 officers in the field over a 24-hour period with the existing force supplemented by over 3,600 officers brought in from police forces in England, Scotland and Wales. http://www.thejournal.ie/psni-g8-drones-953869-Jun2013/ Bookmark It Hide Sites
Trimble’s new UAS targets big survey, geospatial projects
Holding thumbs that the FAA will come through for them in 2015, Trimble unveils its latest wing. Sunnyvale, Calif.-based, publicly traded (Nasdaq: TRMB) Trimble, with $2 billion in 2012 revenue, uses positioning technologies – GPS, lasers and optics – to focus on applications requiring position or location, including surveying, construction, agriculture, fleet and asset management, public safety and mapping. Like the X100 but better Just like its predecessor, the Gatewing X100 – the market’s first commercial aerial imaging rover – incorporates mission planning, automatic field image acquisition and fully digital and automated image processing software. Trimble acquired privately-held Gatewing, a Belgium-based manufacturer of lightweight UAVs for photogrammetry and rapid terrain mapping, in April 2012. The UX5 carries a Sony NEX-5R mirrorless, 16.1-megapixel camera with a fixed focal-length external lens, which has a surface area nearly nine times that of the Ricoh camera carried on the X100, which was already 1.5 times larger than the biggest on the market at the time. The large field of view from the camera allows the rover to cover 50-75 percent more area to enhance efficiency and reduce operational costs. In addition to the increase in flight efficiency, the Trimble UX5 is capable of producing [...]
Washington’s $10B Unmanned Industry
By Rick Anderson Tad McGeer, multimillionaire godfatherof the state’s drone industry, was heading home the other day from his office in the rain-swept Columbia River Gorge town of White Salmon when he picked up his cell phone and dialed a Seattle reporter. In an earlier e-mail exchange, the reporter had asked about the growth of drone manufacturing in Washington, and McGeer had written back, “Are you jumping on the hype bandwagon, or do you want to discuss reality?” The hype he referred to was the drone-phobia that hovers over any discussion of unmanned flying vehicles, from the small model-sized planes that buzz Seattle neighborhoods to the multi-ton aerial robots that are used in war and prowl Washington’s northern border. To McGeer’s dismay, the public doesn’t seem to like them much—the airborne snoops fly right up and peek through your window, don’t they?—even though civilian drone use is growing and the Pentagon is expanding its drone air force, including four bases in the Evergreen State. Assured by the reporter that reality rocks, McGeer agrees to call. “I’ve got about a 20-minute drive,” said the 56-year-old Stanford aeronautical engineer, steering towards Hood River, Oregon, across the old two-lane toll bridge stretching three-quarters of [...]
GA-ASI successfully demonstrates enhanced sensor dissemination capability in U.S. Navy exercise
General Atomics Aeronautical Systems, Inc. (GA‑ASI), a leading manufacturer of Remotely Piloted Aircraft (RPA), tactical reconnaissance radars, and electro-optic surveillance systems, today announced its successful participation in the recent U.S. Navy Trident Spectre experiment conducted at the Joint Expeditionary Base Little Creek-Fort Story, Va. During its May 8-18 participation, GA-ASI operated a Predator® B surrogate (King Air 200) equipped with Predator B-type sensors including GA-ASI’s Lynx® Multi-mode Radar and FLIR’s Star SAFIRE 380HD Electro-Optical/Infrared (EO/IR) imaging system. The Predator B surrogate leveraged Lynx to detect ground-based moving targets, and GA-ASI’s Claw® payload control software automatically cross-cued, or slewed, to the Star SAFIRE for target visual identification. This next-generation data dissemination capability allowed naval commanders to review data rapidly, modify follow-on mission flight planning, and demonstrate ad-hoc mission re-tasking of the aircraft directly by commanders based in the Tactical Operations Center (TOC). Sensor imagery was also simultaneously streamed to a host of U.S. government entities in real-time. “Our primary goal was to provide all-weather, day/night Lynx radar and EO/IR data on moving ground targets and disseminate that information to the Navy’s shore-based TOC,” said Linden Blue, president, Reconnaissance Systems Group, GA-ASI. “The mission was successfully executed and marked a historical milestone by demonstrating the [...]
Teal Group Predicts Worldwide UAV Market Will Total $89 Billion in Its 2013 UAV Market Profile
Despite near-term U.S. budget cutbacks, Unmanned Aerial Vehicles (UAVs) continue as the most dynamic growth sector of the world aerospace industry this decade, report Teal analysts in their latest integrated market analysis, during the opening of the 50th Paris Air Show. Teal Group’s 2013 market study estimates that UAV spending will more than double over the next decade from current worldwide UAV expenditures of $5.2 billion annually to $11.6 billion, totaling just over $89 billion in the next ten years. (For further details and study availability, contact the respective Teal sales representative in your area at http://www.tealgroup.com/). “The UAV market is evolving, it is becoming an increasingly international market as it grows,” said Philip Finnegan, Teal Group’s director of corporate analysis and an author of the study. “UAVs have proved their value in Iraq and Afghanistan and are being sought by a growing number of militaries worldwide.” “The Teal Group study predicts that the US will account for 65% of the worldwide RDT&E spending on UAV technology over the next decade, and 51% of the procurement,” said Teal Group senior analyst Steve Zaloga, another author of the study. The tenth edition of the sector study, World Unmanned Aerial Vehicle Systems, Market Profile [...]
