The Wilga's design incorporates an air-powered starting system for one. It looks complex, but it has one advantage in that batteries are almost worthless in extreme cold. The landing gear incorporates a short trailing beam at the end of each main gear strut so that its wheels recoil up and rearward, enhancing its ability to handle rough, off-airport landings. Engine cooling is designed to cope with wide air-temperature extremes, long climbs and rapid descents. The cowl shutters, manually operated by a knob in the cockpit open fully to cool the 620-cubic-inch radial on a climb, then close tightly so the airplane can perform its patented 4,000fpm descents without warping the cylinder heads. The airplane is not only adapted very nicely to hauling sailplanes aloft but also to winter operations without fancy cold-weather kits. The engine will run on anything from 70-octane fuel up. A gear-driven supercharger provides a constant boost of about three inches, and it has a two-blade constant-speed prop.

Developments of the Wilga 35 have included the Wilga 35A intended for aeroclub use; the Wilga 35H floatplane fitted with Airtech (Canada) LAP-3000 floats; the multi-purpose Wilga 35M fitted with a 260kW M-14P radial engine, flown in prototype form in 1990; the Wilga 35P tourer or air-taxi version; and the Wilga 35R agricultural variant. A version generally similar to the Wilga 35, but meeting US FAR Part 23 requirements, is designated the Wilga 80. The first of these flew on 30 May 1979, and is available in three versions, the 80A, for aeroclub use, the 80H floatplane, and as the 80R for agricultural use. A more radical redesign, originally identified as the Wilga 88, has become the P.Z.L. 105 Flamingo. The Wilga 35 and 80 remain in production in 1993, by which time P.Z.L. had sold around 900 variants to countries around the world. Wilga 1
