The Eaglet, designed for kit building, first flew in 1975. It has a retractable main wheel, and uses spoilerons for roll and glidepath control.
The BJ-1b Duster is a development of the earlier 41.5 ft. span BJ-1 Dynamite (designed by Ben Jansson and Hank Thor). Approximately 400 sets of plans and 150 component kits have been sold to homebuilders. The Duster is entirely skinned in plywood. In accordance with former OSTIV rules it has terminal-velocity-limiting dive brakes (216 kph/…

The Dragonfly was an early self-launching sailplan whose marketing was sponsored by the Nelson Engine Company as a vehicle for their two- cycle four cylinder engine. The result was an under-powered sailplane. The Dragonfly features a fully retractable tricycle landing gear with stearable nosewheel, dual control and a ratchet- wire pull starter in the cockpit…
The Dottie S was begun as a high school project and completed in 1957 at Mississippi State University with the help of Guy Storer of the Raspet Flight Research Center. The wings were based on the shorter ones of the Schultz-Midwest MU-1 while the horizontal tail was based on the Laister-Kaufmann LK-10A and the vertical…
The Elfe series started from a 9 m sailplane designed by W.Pfenninger before World War II. A new design was introduced by him in 1947 to become the Elfe 2, probably the first sailplane with a laminar flow airfoil. Subsequently the series was further developed by Markwalder to become the Elfe PM-3 (brought to the…
eta is the symbol for efficiency (h ). It is also the name of one of the most ambitious large projects in German glider manufacture. The project contains several new ideas and will certainly cause a sensation. In approximately one and a half years from now, the self-start capable two-seater with the tremendous wingspan of…
The V-1 is a scaled down version of the bomber and transport flying wing prototypes. Which were produced by Northrop near and shortly after the end of World War II. It differs from these by the addition of a vertical tail surface. Control of both pitch and roll is accomplished by rotating wingtips which make…
The flying plank was developed in 1954 by Al Backstrom assisted by Phil Easley and Jack Powell as an attempt to combine minimum size with reasonable performance. The prototype EPB-1 was used for drag reduction tests at Mississippi State University. Plans for the –1A development were sold and a number built, most with twin wingtip…
