ACM Loiter (GPS) Hold Traditional Helicopter

Posted on September 3, 2011 at 4:08pm 6 Comments

 

 

Firstly thanks to Jason for his New Alpha code. 2.0.40. Randy for all the help and Martin who keeps supplying tea

The new control laws that he has implemented work really well. The oscillations have virtually disappeared in stabilise, and Loiter held for over 8 mins with only very slow drift, had to bring the heli back to the start point…

Traditional Helicopter Stabilise & Loiter Test

Posted on August 25, 2011 at 1:46pm 5 Comments

 

 

The aim this evening was to prove the new flybarless head with the ACM, and whether it would make a good deal of difference to the flight characteristics. We flew a full 5 min flight which is pretty good as the Heli is quite heavy now with all the extras fitted to it. Also i use a separate flight and main Power battery. a 2700mah 2cell and a 5000mah…

Arducopter Traditional Heli Plus Quad

Posted on August 13, 2011 at 5:00pm 8 Comments

I met up with martin today (buildyourowndrone.co.uk) to take some video of my Arducopter Traditional Heli and his Quad.

I have got rid of all the wobbles and oscillations, After a few days of talking to randy, he made some changes to the code in the trunk (svn?) you will have to excuse my ignorance. I uploaded it and could see that the changes he made had…

Traditional Helicopter ArduRazor 600

I finally managed to fly my Arducopter Modified Helicopter. Very pleased with todays test. Only hovering but its a great start. I have been battling severe ocscillations. Its rock sold now. After lots of work and late nights.

So the next step is to get some footage and add it here.

The plan is to finally…
