Novarossi have introduced their new Mitro 35 GT5/17 .21 nitro engine. The updated powerplant features a new sleeve with five transfer ports and exhaust booster ports. The special shape and positioning improve internal fluid dynamics to maximise performance while the crankshaft also received an update to increase mixture flow and reduce internal turbulences. Crankshaft balancing is carried out using tungsten inserts and a silicone inlay further enhance acceleration. Included with the package is also an updated 3-needle carburettor for improved idling and also quicker return to lower RPM.
