Plan - 1450 Slingsby T.21 Sedbergh
The Slingsby T.21 is an open-cockpit, side-by-side two-seat glider, built by Slingsby Sailplanes Ltd and was first flown in 1944. It was widely used by the RAF Air Cadets and by civilian gliding clubs, and is still a very popular machine. The T-21 Sedbergh glider plan is 1/5-scale size. It is designed after the two-place full-scale glider. The model has a wingspan of 130 inches when finished. It is a built-up balsa, plywood and spruce model, with miscellaneous hardware required.
