O.S. Speed B2102 low-profile buggy engine

On show during this week’s Tokyo Hobby Show is O.S. Engines’ new Speed B2102 3.5cc nitro buggy engine. The most noticeable part of the power plant is its low-profile cooling head that sits about 17mm lower than standard, making for a greatly lowered centre of gravity without sacrificing cooling performance. Also new to the B2102 are the carburettor, crankcase, combustion camber insert and more. The engine will become available from December as engine only or including a T2090SC muffler.
