About the Alpaero Sinus

The Alpaero Sinus is a European ultralight motorglider that blends efficient cross-country soaring with powered flight capability. Built in Slovenia and certified under European ultralight regulations, the Sinus features a high-aspect-ratio wing optimized for glide performance (glide ratio approximately 1:27) while retaining a Rotax 912 piston engine for self-launch and sustained cruise. Its composite construction keeps the maximum takeoff weight under 600 kilograms, allowing operation under Light Sport Aircraft rules in many jurisdictions.

The type is popular among European pilots seeking an economical platform for both local soaring and modest touring, with a cruise speed around 95 knots and endurance exceeding four hours on internal fuel. The Sinus competes directly with the Pipistrel Virus and other motor-glider designs in the ultralight category, offering a practical compromise between pure sailplane efficiency and the flexibility of powered flight. Registration prefixes like D-M (German ultralight) and OK-UUO (Czech ultralight) reflect its primary market in Central Europe, where it serves flight schools, private owners, and soaring clubs.
