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.

The aircraft was marketed as plans and as a kit by Falconar Avia of Edmonton, Alberta, Canada. Plans are now supplied by Manna Aviation of Australia.^[1][2]

Design

The Turbi is built using all-wood construction. The wing uses a two-spar design. It uses slotted ailerons.^[3]
