ROTO 85 FS UAV Engine EFI 550W
Introducing a twin-cylinder four-stroke engine, air-cooled, controlled by a CDI unit with a preset advance curve for smooth operation, designed for use in UAV projects. It is highly sought after for UAV, V-TOL, and Heli projects, where this engine is most commonly used due to its low weight, high performance, and very low fuel consumption. The Roto 85 FS UAV has a long lifespan, tested by dozens of successful projects. This engine is the most sought-after type in the UAV sector.

| Features | Start generatorStart generators under the trademark „STG Roto“ 1000W and 2000W.  + Remote start & stop + Hybrid system + Hybrid boost  GeneratorGenerators under the trademark „AL Roto“ in range 300 up to 2000W. + Low purchase price + Stabilized voltage energ Electronic Fuel InjectionThe big advantage of Electronic Fuel Injection is the possibility to achieve very low fuel consumption. EFI installed on a Roto 125 FS engine achieves fuel savings of up to 40% compared to a carbureted engine. The economic cost of an EFI Roto is higher than a carbureted engine, but if your project reaches series production the purchase price of the EFI will drop significantly due to the use of EFI LIGHT / Production. With the production version it is assumed that equipment such as Lambda probes, temperature sensors and adjustment modules will no longer be required for the EFI setup. At the time of series production, the economic costs will be offset by the lower price of EFI Light and the low fuel consumption. Another major advantage is the flight levels above 5000 meters above sea level.  + low fuel consumption + Electronic control + flight level 5000 m.a.s.l.  CarburetorCarburetor is a very good and inexpensive option for projects flying at flight levels below 2000 meters above sea level. For missions lasting up to 5 hours, the carburetor is a good choice for both project cost and fuel economy.The carburetor can be set up directly for your project, where we at Roto Motor Ltd will preset the PWM values for your mission and determine the best conditions for your engineers to control the throttle of the carburetor, in PWM values.By maintaining basic parameters such as CHT and EGT temperatures, you can count on reliable and inexpensive operation of ROTO four-stroke engines. + Low purchase price + Simple control |
