SP-28 Series

The Sky Power SP-28 CR is still our most requested system and particularly suited for fixed wing aircraft on the upper end of the “below 55 lbs” or “up to 25 kg” class UASs. The Sky Power SP-28 CR engine is equipped in the standard configuration with one spark plug and a single ignition unit. The carburetor is rear (CR) mounted.

The cylinder and crankcase are casted aluminum and have been manufactured in its current form for over a decade. One customer is running this propulsion system for 10+ years and accumulated more than 1,000,000 flight hours, it is a reliable work horse in all operational scenarios.
