I remember seeing Brett Buck at the '93 NATS with a full fuselage Imitation. Bill <><
Heck, you will see me with the same plane at the 2006 NATs. It will be a backup, but it was good enough for second at the NWR about a month ago. Same airplane got me the 595 at the Knight's Joust in 1994. It's pretty good.
This airplane definitely stretches the definition of the Imitation to the limit. The only thing left of the original design is the fixed portion of the wing. Other than that, the flaps are about 75% larger, the tail moment is 19.5 instead of 18, the tail percentage is significantly larger. It's a long story to explain how it got that way. It's also debatable whether the mods are really an improvement, but it seems to work.
