The Elfe 17a is a wooden / composite construction glider that was built in the early 1970s.
It was designed by the Swiss architect Albert Neukom , who has developed and built numerous gliders since the mid-1950s. A mix of materials for various components on the aircraft is typical of Neukom's designs. In the Elfe 17, for example, the wing spar is made of aluminum and the hull is made of plywood. The glide ratio of 40 is comparable to that of gliders in GRP construction .
The cantilevered shoulder wing with cross tail, pendulum rudder and a rudder with compensation surface has a retractable canopy and retractable landing gear .
