UAV ENGINES

Roto engines are tested in harsh conditions simulating real missions from takeoff through the flight phase to the landing sequence. We know that the engines are operated in harsh conditions with dusty environments, but also in rain and cold weather. We have tested all these conditions over the last 10 years on our Roto engines. Based on this experience, we strive to reach 300 hours TBO. In every cooperation with the customer we try to get feedback from flight tests, based on which we can achieve TBO with a great range. ROTO engines are designed based on many years of experience with a focus on high combustion engine life, long TBO and reliability. Roto Motor Ltd. Czech Republic is the market leader in the market of internal combustion engines for UAV projects.
