Thanks Dave. Actually, the bipe (I call it the Stealth Camel 'cuz it's got see-through covering) was a design exercise to have good performance including touch n' goes, taxiing, good take-offs, etc. with an exhaust sleeve-throttled .020 Tee Dee.
It's the lightest construction/appearance package I could come up with at the time and looks closest to a Sopwith Pup fuselage & empennage with Camel wings. I hate them backward wingtips on the 'Pup.;)
