There are many primary gliders in the U.S. some in museums, some in storage, some occasionally flying. The types include the Zogling, SG 38, Mead, Rhon Ranger, Schweizer SGP 1-1, Waca, Cessna, Reynolds, Dagling and Slingsby T. 38 Grasshopper and one-offs constructed right up to the 1960’s (e.g. Jongblood). The Detroit Gull primary glider was produced by Detroit Aircraft in the early 1930’s with ATC No. 1. Primary gliders are not listed seperately due to similar background and characteristics, and constraints of space. Some primaries were modified by incorporation of a nacelle around the completely open cockpit, both to give some protection to the pilot, and to improve performance. The Dagling has been chosen, partly at random and partly because an example exists belonging to the National Soaring Museum, as represntative of this class of early glider. The Dagling design was a 1930 rework by Reg Dagnall’s RFD company and also Slingsby (type 3), but most were built from plans. Aero Club Albatross in New Jersey built one as their first glider, and Gus Scheurer recreated a Dagling for the National Soaring Museum. After World War II, Slingsby converted T. 7 Kirby Cadet T.X. Mk. 1’s into T.38 Grasshopper T.X. Mk. 1’s by adding Cadet wings to a new primary fuselage. The Royal Air Force used 115 T. 38’s in its Air Cadet training program. Primary gliders were mainly used for basic trainging, before the pilot proceeded to a higher performance secondary glider. Part of the hazard associated with this kind of solo traing was removed by the use of the German-invented pendelbock, or tripod, on which the primary glider could be suspended close to the ground enabling the student to experience the effect of the control while pointing into wing. The Vintage Sailplane Association has plans for the Ranger, Reynolds, SG 38 and several other primary gliders
