Power and Reliability: Rotax 912 ULS Engine
Proven Performance
The STOL CRUISER is powered by the renowned Rotax 912 ULS engine, a proven powerplant trusted by pilots worldwide. This engine delivers reliable performance across a wide range of operating conditions, from high-altitude mountain flying to sea-level operations.
The Rotax 912 ULS provides the perfect balance of power, fuel efficiency, and reliability for the STOL CRUISER's mission profile. Its proven track record in ultralight and light sport aviation makes it the ideal choice for this versatile aircraft.
Future-Ready Design
While the standard configuration features the Rotax 912 ULS, the STOL CRUISER's design accommodates more powerful powerplants. This forward-thinking approach ensures the aircraft can evolve with advancing engine technology and meet diverse pilot requirements.
The flexible engine mounting system allows for future upgrades, providing owners with long-term versatility and investment protection.
Wing Design: Engineering for Performance
The STOL CRUISER's wing represents a significant engineering achievement, designed as a self-supporting structure without oblique struts. This clean design reduces drag and improves overall aerodynamic efficiency, contributing to the aircraft's impressive cruise speed.
Trapezoidal Design
Optimized planform for balanced lift distribution and efficient high-speed cruise performance.
Leading Edge Slots
Integrated slots enhance low-speed handling and reduce stalling speed for safe short-field operations.
Fowler Flaps
Advanced flap system increases both wing area and camber, dramatically reducing landing speeds.
Fuselage Design: Visibility and Efficiency
The STOL CRUISER's fuselage geometry has been carefully optimized to provide exceptional pilot visibility at higher angles of incidence. This is crucial for short-field operations where precise control during approach and landing is essential.
The all-metal construction ensures durability and longevity while maintaining light weight. The rear fuselage is specifically tailored to accommodate tail surfaces in a traditional arrangement, providing predictable handling characteristics that pilots appreciate.
The spacious cabin features a width of 1.2 meters, providing comfortable side-by-side seating for two occupants. This generous interior space makes long cross-country flights more enjoyable while maintaining the aircraft's compact external dimensions.
Landing Gear: Rugged and Reliable
The STOL CRUISER's landing gear system is engineered to handle the demanding requirements of short-field and unpaved runway operations. The robust design provides excellent ground handling characteristics while absorbing the stresses of operations on challenging surfaces.
