auto drift correction problem

Hello,I´m on the way to build a very special copter for aerial video shoots. So for me the the best possible stability is very important to get a good result.So tow years ago I started to build a Copter that always fly in a horizontal alignment, using extra props for the vertical acceleration.The first one I build was based on MultiWII FlyDuino that is flying well.Now I build a bigger one based on Arducopter. But with that software I have a problem.For me it look´s like there is a function in…See More

"TAKEOFF STABILITY WITH 2.9.1b I have an issue with run up and takeoff stability. My F330 is difficult to get off the ground nicely i.e. with no pitch/roll manual interaction. Once it is in the air, it works well. Alt_Hold also works smoothly. It…"

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.

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

As I already mentioned on the first page, mygoal was to construct a boat that could drive for at least 4 hours without charging while I could catch some fish :-). To reach that goal, my boat should weigh around 4 kg and the capacity of the batteries should be quite high. After a lot of searching in the internet, I…

Using Unmanned Aerial Vehicles for Environmental Monitoring

Using Unmanned Aerial Vehicles for Environmental Monitoring

By Rodolfo Quevenco, IAEA Division of Public Information It’s a sight you don’t often see at the headquarters of the IAEA in Vienna. With a whirr of its 6 rotors and a puff of dust, a remote-controlled vehicle takes off and hovers above the heads of Agency officials and staff, and then flies along a pre-determined path. The cylindrical, clover-shaped aerial vehicle with a mounted camera on board is one of the latest breed of unmanned aerial vehicles (UAV) – commonly known as “drones” – available today. The demonstration was held as part of a consultancy meeting on the parameters for using UAVs for rapid environmental monitoring held at IAEA headquarters from 14 to 17 May 2013. The consultancy meeting was organized by the IAEA’s Physics Section within the framework of the IAEA Action Plan on Nuclear Safety. One of the aims of theAction Plan is to ensure the ongoing protection of people and the environment from ionizing radiation by facilitating the use of available expertise and techniques for environmental monitoring. The meeting was attended by environmental mapping and UAV experts from Germany, Japan, Switzerland and the USA to review and evaluate the current state of detector technology and methods, particularly in [...]

OSU Students Design Storm-Penetrating Drones

OSU Students Design Storm-Penetrating Drones

STILLWATER, Oklahoma - Engineering students at Oklahoma State University have designed storm-penetrating unmanned aircraft. School officials say the drones are designed to fly into thunderstorms, including the super cells that spawn tornadoes and obtain meteorological data vital for weather forecasting. “Oklahoma, along with many regions in the U.S., has to deal with severe weather year-round, but the often violent thunderstorms witnessed in the springtime are particularly worrisome,” said Jamey Jacob, a mechanical and aerospace engineering professor who supervised the project. “Better prediction methods can save lives, but this also requires more data about how storms form.” The aircraft were designed by students in the school’s MAE department. The drones will collect information about weather systems that can be used for both immediate forecasts of the storm’s path and strength and for predictive models. Three teams of students, the Barnstormers, the Flying Honey Badgers and the Stormtroopers designed an aircraft with corresponding onboard sensors, ground control, launch and recovery systems that could be deployed from a catapult or unimproved surface, such as a dirt road. The drones are controlled by a pilot on the ground and relay data back to a ground crew. Bookmark It Hide Sites

Prince William Panel Talks Use of Unmanned Drone Aircraft

Prince William Panel Talks Use of Unmanned Drone Aircraft

By CONNIE MOSER For Potomac Local News LAKE RIDGE, Va. – A recent Prince William Committee of 100 meeting on Wednesday addressed the topic of small, unmanned aircraft. You may refer to them as drones, but according to a one member on a panel of experts, moderated by Ben Wolfgang, from the Washington Times that term; “drone” is equivalent to a four letter word. Carl Schaefer, Director, Small Unmanned Aircraft System Products, Aurora Flight Sciences Corp., Manassas, VA prefers the acronym; “UAS”. Most residents who at expressed concerns regarding privacy when the FAA declared UAS (Unmanned Aircraft Systems) are ready for prime time. The Federal Government is not running rampant, without oversight regarding UAS, as there are many watchdogs ensuring that no one tramples the Fourth Amendment to the Constitution, according to those who spoke at the meeting. Ben Cline, R-Lexington, a sixth term representative to the Virginia House of Delegates, is one of those watchdogs. Cline is concerned the government not overstep the boundaries set forth in the Constitution. Cline showed a healthy skepticism when an audience member asked, “Why should we trust the government?” Delegate Cline’s response was, “You shouldn’t!” Additional concerns about privacy were addressed by Amie Stepanovich, Director, Domestic Surveillance [...]

Ar.Drone 2.0 joins the Royal Air Force

Ar.Drone 2.0 joins the Royal Air Force

Parrot is supporting the RAF Rally Championship for 2013 with a Parrot AR.Drone 2.0 Quadcopter. As serving members of the Royal Air Force the team know a thing or two about aviation, aircraft and drones and they think the Parrot AR.Drone 2.0 Quadcopter is a magnificent flying machine and perfect for capturing the unique action from the RAF Rally Championship. This started recently when the RAF Rally Team has its pre-season training camp in Rorbacksnas, Sweden. They spent 5 days driving rally cars at full speed around a purposely designed ice stage — the Parrot AR.Drone 2.0 was used in the sub-zero conditions to capture unique footage from angles that other cameras just don’t allow.
