You can apply aerodynamic theory and rhetoric all day long, but the bottom line is, how do YOU like the way your plane flies?

Case in point: I have built about six Ultra Sports since the early 90's. The plane is designed to have cap strips over the ribs. I have built the wing in the following configurations:

Cap Strips
Fully sheeted
Sheeted top, Cap Strips on bottom

And I built one "Lite" version where I went through painstaking measures to build it as light as possible.

The results: I like the way the fully-sheeted wing flew the best. I liked the "Lite" version the least (in fact, I gave the plane away after two flights)
