Development and Design
The UL-2000 Flamingo emerged from AEROS SRO's evolution from a Ukrainian hang glider cooperative in the late 1980s into a sophisticated ultralight manufacturer. The company, originally known as ITACO-CENTER co-operative, had produced approximately 150 hang gliders by the early 1990s before expanding into paragliders and powered aircraft. By 2005, AEROS had manufactured over 3,000 wings and established a European service center in Eisenach, Germany.
Designed specifically to comply with Fédération Aéronautique Internationale microlight regulations, the Flamingo was engineered as a touring aircraft prioritizing performance and comfort. The development team at AEROS SRO created an enclosed cockpit with a generous 43-inch cabin width, accommodating side-by-side seating in relative comfort for the ultralight category. The aircraft made its public debut at the AERO show in Friedrichshafen in 2001, marking AEROS's entry into the competitive European ultralight market.
Technical Innovation
The Flamingo's cantilever high-wing design incorporates several advanced features uncommon in the ultralight category. Its 28-foot, 3-inch wingspan supports flaps across the wing's trailing edge, operated by push-rod controls that also manage the elevators and rudder. This control system contributes to the aircraft's exceptional performance envelope, enabling a maximum speed of 150 mph while maintaining a gentle stall speed of just 39 mph.
Composite construction throughout the airframe reduces weight while providing structural integrity necessary for the aircraft's high-speed capabilities. The wing area of 113 square feet generates sufficient lift for the 992-pound gross weight, resulting in a climb rate of 1,280 feet per minute. The 20-gallon fuel capacity provides adequate range for cross-country touring, the aircraft's intended mission profile.
Powerplant Options
AEROS offers the Flamingo with four different engine options to suit varying performance requirements and budgets. The standard powerplant is the 100-horsepower Rotax 912ULS, a four-stroke, liquid- and air-cooled four-cylinder engine that has powered ultralight aircraft since the late 1980s. This Austrian-manufactured engine, weighing between 128 and 135 pounds, delivers 95 to 100 horsepower at 5,500 to 5,800 rpm.
Alternative powerplants include the four-stroke Verner 1400S, the 110-horsepower Hirth F30 two-stroke, and the 65-horsepower Hirth 2706 two-stroke. The variety of engine options allows operators to optimize their aircraft for specific missions, from economical touring with the smaller Hirth engine to maximum performance with the larger powerplants. The Rotax 912ULS remains the most popular choice, benefiting from widespread parts availability and service network support.
Performance Characteristics
With the Rotax 912ULS installation, the Flamingo achieves a cruise speed of 110 mph, making it one of the faster aircraft in its category. The 6.5 meters per second rate of climb provides strong performance for obstacle clearance and rapid altitude gains. The aircraft's speed range spans from its 39-mph stall speed to its 150-mph maximum velocity, offering pilots considerable flexibility in flight operations.
The tricycle landing gear configuration enhances ground handling characteristics, particularly important for the aircraft's intended role as a touring machine visiting diverse airports. The enclosed cockpit protects occupants from weather during cross-country flights, while the side-by-side seating arrangement facilitates instruction and shared flying experiences.
Production and Market Position
Manufacturing began in 2001 at AEROS SRO's facilities in Kutná Hora, Czech Republic, and has continued without interruption. While exact production numbers remain undocumented, the aircraft has maintained steady availability with ongoing builds supported by propeller options and parts supply. Customer feedback from as recently as 2015 indicates active operation and support for existing aircraft.
The Flamingo occupies a premium position in the ultralight market, offering performance and construction quality typically associated with certified light aircraft. Its composite construction and high-speed capabilities distinguish it from fabric-covered competitors, though at presumably higher cost. The aircraft serves pilots seeking maximum performance within ultralight weight and certification constraints.
Current Status
AEROS continues operations under its original name, maintaining an active website and product support for the UL-2000 Flamingo. The company's evolution from Ukrainian hang glider manufacturer to Czech ultralight producer represents successful adaptation to changing market conditions and regulatory environments. Production capability remains established in the Czech Republic, with European service support through the German facility.
The Flamingo's two-decade production run demonstrates market acceptance of its high-performance approach to ultralight design. While not achieving the production volumes of simpler ultralight designs, the aircraft has carved out a niche among pilots prioritizing speed and comfort in their recreational flying activities.
