A couple months ago I was testing ArduPlane and some of the different modes. I was not getting on very well in FBW-B* mode. If you look at the image below. You will see the purple track. I was loosing altitude and I couldn't understand why. You can see just before the path goes red, I'd lost a lot of…

Nicknamed "Laurel and Hardy", for reasons that should be obvious.

Everything calibrated...time to get the PID's done! Well..once it stops raining and snowing here in Switzerland. :-(

Some build annoyances, which I'll go into in an additional post.

Laurels bits…

Thanks to Ramon for pointing this project out. 

Because the latter one of condor drone tests went very well in the navigation, I decided to mount the camera aboard the condor photography for mapping and the results appear promising.

Dear Friends,

on VirtualRobotix we are working in new advanced platform based on GolaKele Frame and VR Brain Gold and PRO configuration.

This is first example of service where we use the our multicopter for roof inspection.

In the test use also Wookong DJI on other Hexa for doing some comparison on two different kind of…

Several months ago I started working on a system called Afterflight to organize and browse my tlogs and dataflash logs, sync them with video, and view them along with a map GPS display. It still has a long way to go, but there is a fair amount of working functionality so I figured I'd get it out there…

Here is a short video of the design, build and crash testing of the Game of Drone's Battle Quad.  It's waterproof, bulletproof, and can fly away from almost any crash.

I had a couple of requests for a still shot of the 12-rotor beast that Joe and Justin cooked up, so here it…

This might be a common knowledge, but in the last months I haven't seen a similar post. Maybe someone new to barometers might be interested in this data.

The GPS receivers return altitude data, but this is inaccurate. The error margin depends on the satellite constellation geometry…

Last Wednesday I went out to the field for some flight tests and gains trimming. Other people where flying their model planes there too. We usually follow a counter-clockwise pattern while flying to avoid collisions. That day I was flying especially slow, so when I took the turn, I did so on the spot and…

New lithium-ion battery design that’s 2,000 times more powerful, recharges 1,000 times faster... I'm drooling!

I want to let the APM trigger my camera and the camera I had did not have a port for a remote shutter trigger so I had to remove the button on the camera and solder the 4 points and connected them to a relay switch.

Raw flight footage.

Just to document some early progress in the building of a multirotor Conservation Drone with thermal imaging for wildlife research (last picture shows the quad with a FLIR PS32 camera, yet to be mounted). Apologies for the shaky video taken with an iphone (had to hold on to transmitter with other hand).

Every year or so, some research group posts a video of a "cyclocopter" flying. I'm not sure why (this article suggest they might be more efficient than traditional helicopters, and that people have been pursing them for a…

As is customary and traditional, we celebrate every new 1,000 members here and share the traffic stats. This time it's 39,000!

There were 2 million page views in the last month! (we get around 65,000 pageviews a day on average). It took us just 24 days to get this latest 1,000 members--we're…

Last week(week 5) I tested out a new FPV system using 1.2 GHZ. It works great. The only problem I had was that it was locking out my 2.4GHZ control. So for the video I used my old 72mhz radio. Let's just call it glitch. It glitched me right into a patch of stinging nettles. So I ordered a low pass filter from Readymaderc.com. Then I commenced to building yet…
