I went to a swap meet today and found an autogyro to take home, but I don't know what kind it is. The guy I bought it from said that it was a kit, so maybe you guys can help me out. It's a tractor engine with a single two bladed rotor. Each blade is 23" and the fuse is just under four feet. It's made out of aluminum that's riveted together. The tail surfaces are made of coroplast as well as a piece around the rotor mast. Any ideas? I'll try to post some pics.
