Thanks for the website. We would be using the autogyro as an aside; simply as a platform to test our flight programs. Right now hovering is not important, just flying slowly is. I'm gathering all the info I can for the professor to see if auto's are a resonable alternative to a helicopter since in the project the area of study are the control algorithms and not the platform. The software should, in the end, be universal allowing us to port it to different craft with few minor changes. Because the availability of a large kitted craft seems limited, we would have to design our own. I really liked the G-Stick on the autogyro.com website. That wouldn't be too hard to duplicate. I've built and flow downspout spads before . . . are there any universal rules that apply to the rotor head design? Is there an equation to calculate the angle of attack for the rotor disk? Sorry for the long posts!!
