Novarossi Rolling 7-port 3.5cc off-road engine

Novarossi have introduced their new Rolling 7-power nitro off-road engine. It features a new sleeve with seven transfer ports and exhaust boosters with the patented shape and position of those will improve internal mixture flow to optimise overall performance. Also part of the package is a tuned crankshaft whose design will reduce mixture turbulences while the special front shape improves sealing against fuel leaking. Other fears include the proven R7 conrod, a steel-filled rear cover as well as the patented, shifted composite 3-needle carburettor. The engine is rounded out by the Lighter & Lower Evolution 2 cooling head that sports a 6-bolt design, it will make for a lower centre of gravity and thanks to excessive milling it is also very light of weight.
