The Slingsby T.49 Capstan is a British two-seat glider of the 1960s built by Slingsby Sailplanes as a replacement for their earlier Type 42 Eagle.

Design and development

[edit]

The Capstan is a high-winged monoplane of wooden construction, the last two-seat wooden glider built by Slingsby,[1] intended for both training and general club flying. Side-by-side seats for the two pilots are accommodated in an enclosed cockpit with a one-piece perspex canopy. The prototype T.49A first flew in 1961, and it entered production as the T.49B in 1963.[2] Thirty-four Capstans were built,[1] one of which was fitted with an auxiliary engine with the designation T.49C Powered Capstan.
