if wind blowing on it makes it climb or descend then in could be an aerodynamic effect but I'm pretty sure you have the foam over the bark right? all APM 2.5s come in a case now with foam already installed over the baro.

Hi,I am having trouble getting my signal lost/ throttle failsafe working correctly and hope someone can help me out.The hardware: Turnigy 9XR radio tx, APM 2.5, Spectrum AR8000 rx, Turnigy dlux 40A SBEC speed controller. My understanding of the theory and method to set up throttle failsafe with APM 2.5:1) Set your tx radio up so that the low throttle PWM is below say 950. On my radio I have to turn on extended servo range and adjust my channel one to -125%. this is a low as it will go.2) Bind…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/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)

CU-Boulder organizing effort to establish unmanned aircraft test site in Colorado
Jim Scott, CU-Boulder media relations A state application organized by the University of Colorado Boulder has been submitted to the Federal Aviation Administration for the development of one of six unmanned aircraft systems test sites slated to be established across the United States. Submitted this month, the seventh and final volume of the Colorado application is one of 50 proposals from 37 states for designated Unmanned Aircraft Systems, or UAS, test sites. UAS come in various sizes ranging from hobby airplanes to aircraft with wingspans as wide as commercial jets. While they can be used for tasks ranging from forest fire support and search and rescue missions to oil and gas exploration and military operations, a growing number of science efforts are being undertaken using UAS, said CU-Boulder aerospace engineering sciences Associate Professor Eric Frew. CU-Boulder has one of the most comprehensive UAS science programs in the nation, said Frew, who directs CU’s Research and Engineering Center for Unmanned Vehicles, or RECUV. CU-Boulder’s UAS projects have included monitoring seal populations in the Arctic and charting sea ice changes near Greenland to intercepting storm cells associated with tornadoes in Colorado, Kansas and Nebraska and measuring gaping holes in Antarctic sea ice known as [...]
Infragram: the Infrared Photography Project
A simple, cheap infrared camera which can measure plant health — for geek gardeners, farmers, and open source DIY scientists. What could farmers, gardeners, students or environmental activists do with an infrared camera that costs as little as $35?What is Infragram? Infragram is a simple, affordable near-infrared camera produced by the Public Laboratory community in a series of collaborative experiments over the last few years. We originally developed this technology to monitor wetlands damages in the wake of the BP oil spill, but its simplicity of use and easy-to-modify open-source hardware & software makes it a useful tool for home gardeners, hikers, makers, farmers, amateur scientists, teachers, artists, and anyone curious about the secret lives of plants. What can you do with Infragram? Take pictures to examine plant health in backyard gardens, farms, parks, andnearby wetlands Check on the health of your crops, especially from a balloon or a kite Monitor your household plants Teach students about plant growth and photosynthesis Create exciting science fair projects Generate verifiable, open environmental data Check progress of environmental restoration projects Document unhealthy areas of your local ecology Pretend you have super-veg-powers Near-infrared photography has been a key tool for planning at the industrial and governmental level: it is used on airplanes and satellites by vineyards, [...]
Google acquires kite-power generator
Well I did’nt see this coming. Using lots of UA tech Google invests in yet more cutting edge stuff (ed) Google has acquired a US company that generates power using turbines mounted on tethered kites or wings. Makani Power will become part of Google X – the secretive research and development arm of the search giant. The deal comes as Makani carries out the first fully autonomous flights of robot kites bearing its power-generating propellers. Google has not said how much it paid to acquire Makani, but it has invested $15m (£9.9m) in the company before now. In a statement posted to its website, Makani said the deal would “provide Makani with the resources to accelerate our work to make wind energy cost competitive with fossil fuels”. Rather than use fixed turbines to generate power, Makani has been experimenting with “flying wings” adorned with several smaller turbines that act as propellers as the craft takes off. Makani claims that mounting the turbines on a wing is more efficient as large numbers can be built with fewer materials than traditional tower-based turbines. In addition, the robot wings can land to avoid damage if wind speeds are too high or during bad [...]
Unmanned aircraft can protect crops from locusts
by Gabino Martinez Serrano The world population is growing at a rapid pace. Today we are almost seven billion people and it is estimated that the figure will exceed 10 billion in 15 years. The world’s need for food will double, but the world’s arable land remains the same. Experts say that to increase performance, it is important to plant each crop where it can best develop, increase the yield potential of plant varieties and to reduce adversity posed by pests which have become a real problem. Failure to protect crops from pests would reduce harvests to just over half. Locusts are unique because they undergo a phase change. This means that under certain circumstances related to climate and population density, their behaviour changes and they move, eat and behave as a group, forming gigantic clouds and can travel great distances devouring crops in their path. These pests can affect 20 per cent of the surface of the earth, spreading through Africa, the Near East, and Southwest Asia. More than 65 countries may be at risk of swarms, invasion and reproduction. The last powerful plague occurred in 1988-89, threatening as many as 43 countries, one fifth of the world as [...]
ESCC to use donated unmanned aerial vehicles for science
Ted Shockley MELFA — Launching unmanned aerial vehicles from the Eastern Shore could be a financial plus for the area, and Eastern Shore Community College is positioning itself for an associated educational and training partnership. A link between the two was seen recently when an Aerosonde aerial vehicle donated to the college was unveiled in front of a gathering of staff members and industry experts. “We have something tangible, real, that the students can see,” said College President Linda Thomas-Glover of the unmanned airplane, which from wing to wing was bigger than a typical dining-room table. The particular model was used for years out of Wallops to gather weather data and has flown into hurricanes, said Jon Borcik, a program manager for AAI Corp., which oversees the Aerosonde program. He called it a “coming home mission” for the plane, a fitting place for an aircraft based at Wallops to continue its service. The plane will be used to stimulate an interest in science and also be studied by various college classes. The donation was arraigned by Peter Bale, board chairman for the Association for Unmanned Vehicle Systems International and a former program manager for Aerosonde North America at Wallops. At a [...]
