The ProFe D-8 Moby Dick is a family of Czech pusher configuration, parasol wing, strut-braced, V-tailed, motor gliders that was designed by Oldřich Olšanský, M.Sc, and produced by ProFe as well by several amateur builders according to available plans.

[1] The first glider in the series was the single seat Mini Straton D-7, which was designed in 1988 and first shown in the United States at AirVenture in 1992.

This was followed by the improved single seat Straton D-8 and the D-8 Moby Dick two seater.

The fuselage is of conventional sailplane type in appearance, but the semi-tapered wing is suspended above the fuselage on cabane struts, supported by lift struts, with the pusher engine mounted at the rear of the wing.

The Straton D-8 has a monowheel landing gear, while the Moby Dick has two closely spaced, fuselage-mounted wheels.
