strojnik-s2


Designed by Alex Strojnik, the S-2 uses carbon fiber and aluminum wing spars with fiberglass skins. The fuselage pod is wood skinned with fiberglass, the boom is aluminum and the tail group is carbon-reinforced and skinned with fiberglass. The fixed gear consist of two small wheels in tandem. The Kohler engine drives a foldable propeller. Glidepath control is by flaps.

Designed by Alex Strojnik, the S-2a is a pod and boom pusher with folding propeller. The span is 15 meters and the best L/D is about 34:1. Alex made many excellent soaring flights with his motorglider, including diamond goal distance. A number of these have been built. Plans are no longer available for sale.
