Art-tech, a Chinese maker of very cheap RC aircraft, has launched a UAV division and has some new products that could be interesting.
Below are the specs of the fixed wing autopilot shown above. No pricing or availability is given (I've emailed asking for more info) and the website is a terrible broken mess of missing pages and non-working sections, so I assume the product is not out yet. My own experience with Art-Tech is that its products are pretty low quality, but perhaps this new division is aiming higher. We'll see...
