Druine Turbi

The Druine D.5 Turbi was a light aircraft designed in France in the 1950s for home building. It was a low-wing cantilever monoplane with fixed tailskid undercarriage. The pilot and a single passenger sat in tandem, open cockpits. Essentially a scaled-up version of the Druine Turbulent design, the Turbi shared that aircraft's wooden construction. Again, like its predecessor, it was intended to be able to be powered by a variety of air-cooled engines.
