KANCHANA ATTANAYAKE posted a discussionSoanr MB 1240
I just got my MB1240 Sonar and installed it on my hexacopter. I tested it on CLI sonar testing and it works fine. But when I connect it to MP Flight Data page does not show the sonar readings, I guess it uses Barometer readings.I have checked Configuration page and I have selected XL-EZ0 and have enabled it.I am afraid to test Alt Hold mode as I am not getting my Sonar height on the Flight Data screen.Need some help please.

Loiter bounce erratic motor behaviour !
Hi guys my f450 is now in the air as a test bed for Apm 2.5 and flys extremely well in stab mode !Now trying to sort out my loiter mode : when I engage it we have a slight dip down and then starts to bounce descending and climbing not too alarmingly , and you can hear the motors pulsing up and down to make this happen ? Position seems to hold but alt is a problem . Any help for a solution is appreciated .DarronSee 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)

UAV news from sUAS News
Unmanned aerial vehicles spur demand for advanced foams
Unmanned aerial vehicles (UAVs) are increasingly in the spotlight in trouble spots throughout the world, but they are also finding increased use in civilian applications. In parallel, suppliers of advanced thermoplastics such as Sabic are addressing demands for aerospace grade materials that meet a number of stringent operational requirements. The UAV market has potential not only for military purposes, but also for civil aviation applications, including First Responder support, wildfire mapping, weather monitoring and telecommunications. It is predicted that, if the opening of the National Airspace to civil UAVs occurs in 2015 as planned, the market potential for UAVs between 2015 and 2017 will be around $13.6 billion according to the AUVSI Economic Report 2013. The U.S. military UAV market is similarly expect to expand in the coming years: a report conducted byMarket Research Media states that the U.S. military UAV market is projected to grow at a 12% compound annual growth rate, reaching $18.7 billion in 2018. The report finds that the U.S. military UAV market will generate $86.5 billion revenues over the period 2013-2018. With this market growth, there is an increasing need for advanced materials that will allow the range of UAVs to be extended and their air time to be [...]
Does Navy drone spell end of the Super Hornet?
By Tim Logan Something happened on the deck of an aircraft carrier off the coast of Virginia on Tuesday that could eventually ripple all the way back to one of the biggest factories in the St. Louis area. The X-47B took off. It was a “watershed event,” said the Navy’s head of aviation, the first-ever launch of an unmanned combat drone at sea. While the Northrop Grumman-built X-47B hasn’t yet stuck a carrier landing — one of the hardest feats in all of aviation — Navy officials think that’ll happen this summer, and they hope that by the end of the decade drones will be a big part of their air combat fleet. All of which raises some big questions about the future of the plane that makes up much of the Navy’s air combat fleet today: The F/A-18 Super Hornet. http://www.stltoday.com/business/local/does-navy-drone-spell-end-of-the-super-hornet/article_93958ff4-3776-5132-aedf-db363c1ee8fa.html Bookmark It Hide Sites
Germany Scuttles UAV Program, According To Reports
Agence France Press is reporting that Germany has cancelled a planned ‘Euro Hawk’ UAV programme because it believes European authorities will not certify them to fly in civilian airspace. More from AFP: Germany had “no hope” of seeing the unmanned aircraft, part of a programme that would have cost more than one billion euros ($1.3 billion), approved for use, said the source speaking on condition of anonymity. The European Aviation Safety Agency has said it would only certify the drones to fly over unpopulated areas because of a lack of an anti-collision system to protect airliners, according to German press reports. “The equipment is not ready for approval without immense expenditure,” the source added.

Israel is world’s largest exporter of drones, study finds
By Gili Cohen Israel is the world’s largest exporter of unmanned aircraft, in terms of the number of systems sold, a study has found. Over the last eight years Israel has exported $4.6 billion worth of unmanned aerial vehicles, according to a study by the business consulting firm Frost & Sullivan. UAVs, or drones, constitute nearly 10 percent of Israel’s total military exports. Unmanned equipment exports are a relatively volatile market, the report shows. Israel had $150 million in UAV exports in 2008, a figure which increased substantially in 2009 to $650 million. Exports of the small surveillance planes peaked in 2010, a record year for drone sales, to $979 million. http://www.haaretz.com/news/diplomacy-defense/israel-is-world-s-largest-exporter-of-drones-study-finds.premium-1.524771 Bookmark It Hide Sites
