The Dart Totternhoe was a single-seat secondary training glider produced in the United Kingdom in the 1930s. Three were built, one serving in the RAF.




Design and development


The Totternhoe took its name from a Bedfordshire village; the home of the London Gliding Club is within Totternhoe parish, on the edge of Dunstable Downs. It was a wooden, single-seat secondary glider.
All the flying surfaces of the Totternhoe were straight-edged and fabric covered. The wings and tailplane, both mounted on top of the fuselage, were of constant chord and had blunt tips. No flaps or airbrakes were fitted. Two pairs of lift struts ran from the bottom of the fuselage to the wing spars just inboard of mid span. The near-rectangular rudder was hinged between the elevators, working in a cut-out.
The wooden fuselage was flat-sided, with a blunt nose and open cockpit. Immediately behind the cockpit the upper fuselage was raised to carry the wing, tapering away to the tail. A single main skid and small tail skid formed the undercarriage.
The Totternhoe first flew in May 1936.




Operational history


Three Totternhoes were built; one was later rebuilt by Scott Light Aircraft. One flew with the Air Training Corps as VD199 and was transferred to the Royal Air Force Gliding & Soaring Association in 1950.
