You are looking for a front exhaust engine. Crank induction engines, such as the RS and the Novarossi are rear exhaust. The flywheel side of the engine is the referred to as the front on nitro engines.
These ain't airplanes!
That "jargon" is a left over from the days when there was no such thing as "boat motors" and airplane engines got converted for marine use. These are boats and most, other than Nova Rossi style engines, face to the rear of the boat. Yeah I know it might seem trivial but this has always bugged the crap outta me. :lol: :lol: :lol:
