You know, its kind of funny. I got Mike to reconfigure my Zodiac into a 54mm Radial Flyer. I also had him modify the 3" Scorpion kit I built earlier in the year with a longer MM tube and a standard rear centering ring, so I could build with a tailcone retainer. So, I wonder how many kits he actually sells that are just stock, without changes? It seems like he changes a lot of stuff for a lot of people on a regular basis...
