The full size to model: The Foka 4 was a single-seat sailplane built by the Polish SZD concern in the early 1960s. This one has been built to represent the full-size version at the Glider Heritage Centre at Lasham. In the process, several liberties have been taken in the name of constructional and operational simplicity. The top and bottom airbrakes have been substituted with top surface spoilers instead, the rearward-placed landing wheel of the full-size has been moved forward slightly to be nearer the CG, and the full-length sliding canopy transformed into something more traditional (although you wouldn’t know from just looking at it).
