UAV helicopter

Posted by uzi1978 on May 1, 2008 at 3:21pm

Hi. I have a RC helicopter and I would like to convert it to semi-autonomous flight. I have a Spartan AP2000i, which works great for stabilising the heli; but now I want to be able to tell the heli to go where I want or program a circuit for it to go around. If possible, different altitudes within the circuit would be great. I know that there are a few off-the-shelf solutions, but what would be the best for helicopters?

Thanks for any input.

Altitude hold on the AP200i is an option that I will not be using. This project is not designed for photography it is more for the challenge just to see if I can do it :); ▶ Reply to This

It's a autonav / GPS / IMU / OSD as the title says. Promises to be the ultimate solution. The price is really good too (about US $200 with all options!).
I emailed DREX to check when it would be released; it's still two weeks from now.; ▶ Reply to This

Aside from the craptastic site, is there any evidence that they've ever flown a heli with that? Or anything, for that matter? It looks like the only thing they've demonstrated is OSD.; ▶ Reply to This

They have actually never tested it on a flying platform, but the guy says that the testing will be done this week and if everything is ok, beta units will be available soon after.
Let's wait and see :); ▶ Reply to This

I was looking at the search area for the outback challenge and from what I can work out the uav would need to cover about 38Km's to get there, search the area, and get back. From what I can work out my Trex 450 would only cover about 12km before falling out of the sky with a flat battery. Were you going to try it with a nitro bird or use a plane? I read all the rules and it's a very tough thing to pull off! What are your ideas for an entry?; ▶ Reply to This

I had a nitro before but it was just not practical enough (specially at 2a.m; the neighbours were not very happy :)); ▶ Reply to This

I am wondering if anyone so far has tested the TechFX Motion on a heli yet, I am also very interested in converting a Trex 450 into an autonomous system, but most importantly i would really like to stick to the electric version.. has there been any progress in the longer flight time battery world? anyone flown more than 15-20 minutes on batteries?; ▶ Reply to This
