introducing the SP-275 TS ROS: A Versatile Two-Stroke Engine for UAV Applications

The SP-275 TS ROS is a cutting-edge two-stroke engine featuring a dual spark ignition and a rear output shaft, designed specifically for a wide range of UAV and UAS applications.

Unmatched Power and Versatility

As the most powerful dual-cylinder engine in our lineup, the SP-275 boasts a displacement of 275ccm. This high-performance engine is ideally suited for operations with a maximum takeoff weight (MTOW) ranging from 100 to 150 kg, thanks to its impressive power output and compact design.

Proven Reliability and Extensive Testing

With over a decade of manufacturing experience, the SP-275 has accumulated more than 10,000 hours of operational use. Rigorous internal testing, including over 800 hours on a dynamometer, has simulated various mission profiles and environmental conditions. To date, more than 1,000 units have been produced, demonstrating the engine’s robustness and reliability across diverse global environments—from extreme cold to high heat, and from humid, salty conditions to dusty terrains.

Extended Flight capabilities

Many users report flying continuously for over 12 hours, often beyond visual line of sight (BVLOS), which aligns perfectly with the engine’s target market. The SP-275 features a starter generator mounted on the rear output shaft, making it a dynamic propulsion system adaptable to multiple configurations.
