Apologies for posting 2 aircraft links in a row, but I found this one again after losing it months ago, and I'm not letting it go...

Fly5k is an email list for people who want to build an airplane and go flying for under $5000. One of the many things you can find on their website is links to the last tractor gyroplane design that I couldn't find the last time I talked about tractor gyroplanes, so now I have the complete list (that I know of) of currently available/flying/may fly soon, tractor gyroplanes available.

The website has some other cool stuff buried within (the navigation is not the best, they spend about as much on web design as they do on their airplanes...), like some stuff on the Ladder Pou, which I think is also pretty cool.
