125cc FSI InLine Engine
-
The Roto 125 FSi is a new engine for inline engine aircraft. The design of the engine was aimed at easy installation in an aircraft with a narrow fuselage. Engine performance is comparable to 125cc four-stroke engines, low idle and easy starting is a given.
The engine has been developed with all the experience provided from the Roto - UAV development group and meets the highest possible standards of production quality and output testing.
The Roto 125 FSi is a twin cylinder, four stroke, air cooled inline engine with a single carburettor for ease of user setup. The engine is completely built on roller bearings and is completely maintenance free. Engine lubrication is provided by a system adopted from Roto - UAV and no relubrication is required. The valves and their gears are developed so that their inspection is not necessary before 40 hours of operation.
