Just re-read eness76-RCU's comments earlier about wing loading, and sluggish performance of the Curare and Tipo during slow flight. Like I said, I haven't been around Tipos much, and at least to me, the picture made the wings look like they had more area than they must have, (and the airfoil must be thinner as well).

Jamie--If you're out there-----you were flying a Dirty Birdy at Cave Spring-correct? If so, did it have a 4S, and how did it fly on one. The Dirty Birdy was originally designed with a 2S in mind, (probably with tuned pipe also). It's a fast plane, even without a pipe. I remember I had to make long approaches, and keep the speed up.
