The Roko Aero NG-4 is a Czech, two-seat light sport and ultralight aircraft developed by Roko Aero as a modern composite touring and training type. The design first flew in the late 2000s, with production aircraft appearing mainly through the 2010s. It is a low-wing, tricycle-gear aircraft with side-by-side seating, aimed at private owners, flight schools and cross-country recreational pilots. Its importance in the used market comes from its combination of composite construction, efficient Rotax power and relatively conventional handling compared with many lighter microlight designs.
Typical Roko Aero NG-4 aircraft are powered by the 100 hp Rotax 912 ULS, a widely supported four-cylinder, four-stroke engine used across the light sport aircraft category. Published figures vary by registration category, propeller and equipment, but a representative cruise speed is about 115 to 125 knots. Range is commonly quoted at roughly 600 nautical miles in efficient cruise with reserves dependent on fuel fit and operating profile. Maximum takeoff weight depends on the certification basis, with European ultralight examples typically lower than aircraft configured for the 600 kg light sport class. Service ceiling is generally published in the mid to high teens in feet. Buyers should confirm the exact limitations in the individual aircraft flight manual.
The NG-4 has a compact two-seat cabin with a forward-hinged or upward-opening canopy arrangement depending on build and configuration. Visibility is a strong point of the low-wing layout, particularly for local flying and training. Baggage capacity is suitable for light touring rather than heavy travel loads. Avionics vary widely because many aircraft were delivered or completed with customer-specified panels. Used examples may have traditional analog flight instruments, Dynon or MGL electronic flight displays, Garmin portable or panel-mounted GPS units, Mode S transponders and basic VHF radios. It is not normally associated with factory Garmin Perspective or G1000 installations.
For used-aircraft buyers, the Roko Aero NG-4 usually sits among European composite LSAs and ultralights rather than certified general aviation trainers. Key inspection points include composite structure condition, landing gear attachments, canopy fit, control system rigging, fuel system condition and Rotax maintenance history. Engine time, gearbox inspections, rubber component replacement and propeller records are especially important. Variants and upgrades are most often seen in avionics, propeller choice, interior finish and national weight category. A well-documented NG-4 can offer efficient ownership costs, but parts support, local maintenance familiarity and the aircraft’s exact approval status should be verified before comparing it with more common LSA types.
