I recently wrote my thesis on the topic of using feedback control to provide a vertical position autopilot for an RC helicopter. I used a Gaui EP100 on a test-rig to test the control techniques. The control theory has been designed so that it can be applied to a helicopter of any dimension/number of blades. It is presented in this 26 page document. I hope this can be of…Continue

I'm working on the MultinoCopter project since 2 months. It is a 50x50mm size board with full compatible arduino pro mini architecture and 9DOF imu. I didnt share it because i have to finish the multicopter code before. Now it is working as a serial IMU for the computer based projects (calculating euler angles) and camera stabilizer.
Yesterday i tested the camera stabilization code on the 3 axis. The mount coming from a…Continue
Do you know that chip which goes on Arduino USB Host Shield and ADK boards? Yes, that's Max3421 from Maxim. And that other one which integrate some text based OSD boards? Hmmm... OK it is the Max7456 from Maxim too.
Well, from now on, Maxim will be there on our buddy gyros too.

Finally, I'm posting this project to share.
This is my Quadcopter, a project born because of a passion hobby and a thesis research excuse. :P
4 Outrunner Motors KD36-10XL of 810 [kv] and 24 [A] max.
4 ESC Turnigy Sentry 60 [A]
2 LiPoly Batt. Rhino…Continue
This was a real head scratcher for me, so hopefully this will help others. I have had this radio for 4 years now but never used it as it was so complicated. I decided to RTFM which honestly just confused me the futaba manuals have never been to my liking. I read manuals for a living and compared to some of the rubbish ones this is definitely worse.
I tried all of the other methods listed for Futaba and couldn’t get them to work mostly because there is no "Switch…
When I first got interested in UAVs I took the advice of some of the forum members here and equipped myself with arduino based systems....but I'm a crazy engineer and this approach didn't last long before I had convinced myself I could make a better job of all this if I started from scratch...luckily I also managed to…Continue
For those following this saga, version 6.1 of the AutoQuad board is complete and has passed initial testing. I have taken the 5.0 design and added features that should make it more flexible and expandable while increasing performance. Here is a summary of specifications:
I have been blogging for some time on a tumblr blog called microdrones 2.0 .
Up until now I have been collecting articles and videos of advanced microdrones features.
Soon we will start to discuss what will be the next generation of microdrones, and what
features these next generation microdrones will include.
I opened this blog because for some time I feel that all the microdrone available…Continue

The Modular Testing Platform 2 flies! It flies really well!
I had a great hand toss takeoff, a rough start as I figured out the control sensitivities and trim, some good cruise around time, and a perfect landing.
Any improvements you think I should make? Here is my planned list for the next episode:…Continue

Here are some screenshots from program:
My plane made strange curves during flight. All curves are in the same places. After a very careful check I found an error in APM navigation code. It is now…Continue
Sorry, but I should have made clear that my autopilot design experience relates to fixed wing aircraft so I won't be able to help with rotary airframes.
I should also emphasise that the databse I have relates to PID control only. After a lot of hard work, I have established which stability derivatives the PID gains depend on so that the job for the user becomes one of estimating certain stability derivatives (for which formulae are also available). The PID gains then drop out as…Continue
From Hack-a-day. This ducted-fan beast uses the Sparkfun 6DoF IMU that Jordi wrote the software for. No, it hasn't flown yet.
