85cc FSI 270° InLine Engine
ROTO 85FSI - 270° is not compatible with Muffler 2 in 1
The 270° crankshaft is used exclusively for Warbirds.
The sound of this engine is enhanced by this specially designed crankshaft design specifically for use in WWII fighter aircraft.
The long awaited increase in engine power, by changing the camshaft timing, is also a big change. Another new feature is the use of two carburettors, which take care of separate cylinder filling.
