Now I need to talk myself out of this:
It's called a Radial Rocket. I saw it at Oshkosh last year and thought it one of the most beautiful planes there, but thought it was a one-off custom build. Nope, it's a kit, and it's priced simliar to the F1 Rocket. It uses a 360hp Russian-built M-14P 9 cylinder radial that costs less than the 260hp Lycoming used by the F1 Rocket and the RV-10.
It's a glass kit (as opposed to sheet metal) and I am not at all familiar with working with glass, so that's one reason I can use to get this thing out of my head (although it means that I will have to religously avoid gaining any knowledge whatsoever about glass plane construction) and get back to something more practical.
Still, it's one fine looking plane!
