Designed to meet SHA Homebuilt Sailplane Design Contest criteria: easy to built, low cost, soarable, self-launching, safe, the definitive powered Windrose first flew in 1984. The structural backbone is a hollow plywood box with corners longerons which carry the engine mounts, landing gear and fiberglass cockpit shell. The wings are shaped foam covered with fiberglass, but without a conventional spar. The ‘spars’ are bands of unidirectional roving expoxied into recesses in the upper and lower wing skins, and separated by rows of vertical dowels between the bands to take compression loads off the foam. Ailerons are set inboard from the root to approximately two-thirds span operated by pushrods from the fuselage. The wing structure is free of controls, pushrods, cables ets. Glidepath control is by a triangular spoiler which rises above the wing center section. Both tail surfaces are all-moving. The design comes in 12.65 and 15.0 m. models.
