"The SZD-50-3 PUCHACZ is a two-place training and aerobatics sailplane designed primarily for clubs and soaring schools. The PUCHACZ features beautifully finished fiberglass construction, a quiet and comfortable tandem cockpit, and exceptional handling qualities. This combination of characteristics has established the PUCHACZ as one of the world's favorite two-place sailplanes. The PUCHACZ meets both OSTIV and JAR-22 Utility Category certification requirements... plus, it is approved for extended aerobatics including inverted flight and rolling maneuvers. It is solidly built of fiberglass epoxy composite and protected by durable polyurethane. The spacious cockpit has adjustable front rudder pedals and an adjustable rear seat to accommodate pilots of all sizes in comfort. The one piece side-opening canopy provides outstanding visibility for both pilots. The front instruments are arranged so that they can be easily viewed from the rear seat; however, a rear instrument panel is also available as an option. But the real secret to the PUCHACZ popularity is its excellent handling qualities, both on the ground and in flight. Flight instructors and experienced pilots often describe the Puchacz as the nicest flying two-place sailplane they've ever flown."

"The SZD-51-1 JUNIOR is a single-place club sailplane, with safe and docile handling qualities, specifically designed for early solo and recreational flying. The JUNIOR was designed from the outset as a club glider, not as a fixed gear version of a competition sailplane. It features a large and comfortable cockpit with a more upright seating position that is preferred by club pilots, a fixed undercarriage with an oversized tire to soften landing, and an unusually strong airframe designed to endure 10,000 hours of demanding Club operation. But the key ingredient to the JUNIOR's success is a larger wing area compared to racing sailplanes and an airfoil optimized for safe handling and smooth stall characteristics. The JUNIOR is certainly the logical choice for pilots during the critical early solo stage. But the admiration of the JUNIOR doesn't end there. After developing basic flying skills in the JUNIOR, many pilots continue to prefer it for cross-country and wave flying and even sports class competition."
