well, i have a dogger converted into a high wing and v-tail and it really moves; if you can get it in the pylons is tough to beat. besides we just had a race in fort lauderdale the 10 and 11 of september and the winner of both days was a dogger and one hell of fast time of 1:35 and change. go figure. if you find a kit buy it and don't be afraqid to use it in 424.
