[1] The design is based on the pre-World War II German SG 38 Schulgleiter, modified to use the wing design of the Slingsby T.7 Kirby Cadet glider.
The RAF designated the glider the Grasshopper TX.1, and the first order was for 65 aircraft, which were delivered in 1952 and 1953.
Launch is achieved through the use of a V-shaped bungee or elastic rope pulled by a team of helpers.
The glider can also be mounted on a pivoting tripod pointed into wind for the demonstration of controls.
