The Tailwind is one of the more older Home built designs that is still being flown in numbers today. It proves you can get a lot of performance out of simple shapes and simple construction. Visually the fuselage has very similar lines to the Hyperbipe
I can’t think of a Oshkosh or Sun-N-Fun I’ve been to with out seeing at least one of these aircraft at the show.
You can still build a tailwind today with plans & components from Aircraft Spruce
