The Carbon Dragon first flew in 1988. Altrough meeting the FAI definition of a hang glider, the Carbon Dragon can be launched by foot, aerotow, or bungee. Roll control and approach control are by full span 30 % chord flaperons, and ar least one has been modified by the addition of a pentagonal shaped spoiler in the wing section, similar to that on the Maupin Windrose. It has a fixed main wheel. It complies with U.S. FAA Part 103 rules. In 1994 it became the first sailplane in that class to win against conventional gliders in a scheduled, non-handicapped cross-country contest. Presently 3 world records claimed by Gary Osoba have been submitted for FAI homologation.

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. Specifications in parenthesis are for 15 m. powered versions.

Woodstock was designed with a wing having an 18 % section for the root, 13 % at the tip and no twis. The principal design objectives were low cost and simplicity of construction. Douglas Air was used for all major structural parts and all tail and wing skins were birch. It first flew in 1978 and won the Sailplane Homebuilders Association design contest in 1984. A tail wheel is an option instead of a skid. The main wheel is fixed. Approach control is by wing top surface spoilers. As an option, wings of 13.1 m./ 43.0 ft. were offered for which specifications are given in parenthesis.
