My Az-El mount is sitting on the bench, almost ready to go to the field. But, it doesn't seem ready yet. The hardware was set up and ranges configured with the Maestro Control Center. Azimuth is on channel zero and elevation on channel one. I set the Az to rest at North with permissible swings to South in either direction. This gives me limits at 1385 (-180), 1500 (N) and 1615 (+180). It all works fine with the Maestro Control. I set the MP PWM at "235", the difference between my…See More

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)
This community created the Arduino-compatible ArduPilot, the world's first universal autopilot (planes, copters of all sorts, ground rovers). The APM 2 autopilot hardware runs a variety of powerful free Arduino-based UAV software systems, including:
- ArduPlane, a pro-level UAV system for planes of all types.
- ArduCopter, a fully-autonomous multicopter and heli UAV system.
I'm new to all this--where do I start? Are amateur UAVs legal? (yes)

GA-ASI & UK Partners Validate New Open Payload Architecture During SPCD
General Atomics Aeronautical Systems, Inc. (GA‑ASI), a leading manufacturer of Unmanned Aircraft Systems (UAS), tactical reconnaissance radars, and electro-optic surveillance systems, along with SELEX Galileo (a Finmeccanica company) and Cobham Aviation Services (Cobham), today demonstrated a new open payload architecture during the Sovereign Payload Capability Demonstration (SPCD) held at GA-ASI’s Gray Butte Flight Operations Facilities in Palmdale, Calif. The event included a live flight demonstration over the Pacific Ocean of a GA-ASI Predator® B/MQ-9 Reaper UAS fitted with a SELEX Galileo Seaspray 7500E surveillance radar and showcased the radar’s ability to track targets on land, in the littoral and maritime environments, and from air-to-air. An international audience was in attendance, including officials from the U.S. Air Force, U.S. Department of Homeland Security, and the Ministries of Defense of the UK, Canada, France, Germany, Italy, and The Netherlands. “Today’s demonstration represents a significant step toward the goal of operational independence for Predator B,” said Frank W. Pace, president, Aircraft Systems Group, GA-ASI. “Our open payload architecture greatly reduces integration complexity by allowing payload providers and mission systems integrators to develop their own payload control software and ultimately integrate their own payloads.” The SPCD is part of a joint Independent Research and [...]Mystery object nearly causes mid-air collision
DENVER – The Federal Aviation Administration is investigating a mystery in the sky. A mysterious object flying over Denver nearly caused a mid-air collision Monday evening, 9Wants to Know has learned. As far as investigators know, the mystery object did not show up on radar Monday. Investigators believe this object, whatever it is, could pose a serious safety hazard to planes. Radio transmissions from LiveATC.net confirm a nervous-sounding pilot reported a strange object at 5:17 p.m. Monday. The pilot is heard telling air traffic control: “A remote controlled aircraft, or what? Something just went by the other way … About 20 to 30 seconds ago. It was like a large remote-controlled aircraft. he corporate jet, a Cessna Citation 525 CJ1, was flying at 8,000 feet above sea level over Cherry Creek when the mystery object came close enough to make any pilot nervous. “That’s an issue because now we have something in controlled airspace that poses a danger,” Former NTSB Investigator and 9NEWS Aviation Analyst Greg Feith said. Feith listened to the air traffic recordings and believes the object could be one of three things: - A military or law enforcement drone. - A remote controlled aircraft. - A large [...]Unlicensed pilots operating drone aircraft in Illinois airspace
BY NOLAN PETERSON Medill Reports The FAA said it has met a key congressional requirement to streamline the integration of unmanned drone aircraft, known as UAVs, into U.S. airspace by 2015 – allowing public agencies to operate drones with fewer restrictions. The Illinois Army National Guard has already been operating its Shadow drone in Illinois airspace for six months, but Army regulations do not require certified pilots to remotely operate drones – leaving some aviation experts to question what training requirements should be expected of drone pilots now that their airframes share the sky with domestic commercial aviation. Keith Mackey, an aviation safety consultant, has more than 30,000 hours of pilot flight time in aircraft such as the Boeing 747. He said remotely flying an aircraft can be a lot more difficult than manned flight, and real experience as a pilot is necessary for the safe operation of drones in domestic skies. “I suggest that there is going to be a steep learning curve, with the real potential for accidents,” said Mackey, who has logged more than 6,000 hours as a flight instructor. “A lot of people not steeped in reality and without much experience in aviation are making decisions on paper [...]Saab flight tests heavy fuel version of Skeldar UAV
Saab has conducted flight tests of a heavy fuel powered version of its Skeldar vertical takeoff and landing (VTOL) unmanned aerial vehicle (UAV) in Sweden and Germany. Mikael Franzen, director of Saab Product Area Tactical UAS, said flight testing of the heavy fuel version of Skeldar is progressing according to plan, with several heavy fuel engine helicopters in flight testing stage. “The robust engine and transmission design of the heavy fuel version of Skeldar gives customers a safe and reliable solution for maritime and land operations,” Franzen added. Besides heavy fuel version flight testing, the company is simultaneously conducting maturation and functionality tests to validate Skeldar’s performance. Further development of the Skeldar ILS concept is underway, as well as the functional and configurational development of the Mobile Ground Control Station. The Skeldar is a medium range VTOL rotor UAV designed to conduct surveillance, intelligence gathering, light cargo transportation, and electronic warfare missions, and has been demonstrated and tested from land as well as from a ship’s deck in several countries worldwide.
