Here are a couple of scratch-built Little Bipes. The white/red one is powered by a Babe Bee, and the yellow one is powered by a Spitzy .045.
The Little Bipe, like most other Scientific models, went through various redesigns. My original one in the fifties had a thicker wing and the fuselage was longer in front of the wing. It was powered by a OK Cub (old case .049). This was before the Babe Bee was invented and I THINK the plans showed an OK Cub. When they redesigned and showed the Babe Bee, the fuselage was shortened (to facilitate balance with a tanked engine I guess) and the wings were thinned. If you compare plans to the advertisement drawing, the tail is also mounted differently.
My question is, has the model's empennage EVER really looked like the drawing?
Old farts want to know...
