SKY POWER SP-275 FI TS Engine
SP-275 2-stroke dual cylinder with 275cc is the largest and most powerful dual cylinder, making it the most versatile 2 stroke engine in our portfolio. This power dense propulsion system is most suited to programs from 100-150kg MTOW due to its dimensions and power output. This engine size has been manufactured for over a decade and accrued more than 10,000 operational hours. Internal development and testing has accumulated over 800hrs on dynamometer simulating various mission profiles and conditions. With over 1000 engine systems produced to date, the robustness and durability of the SP-275 has been proven in all global scenarios, from extreme cold to heat, humid and salty conditions to dust.
Many customers fly over 12 hours continuously and BVLOS, due to this engines target market system. With the starter generator mounted on the ROS, the 3W SP-275 is a dynamic propulsion system capable of several different configurations
