FX K5 DC .21 nitro off-road engine

New from FX comes the K5 DC 1/8th off-road competition racing engine. It is based on the 5K and brings all the refinements and improvements based on the experiences gained from the previous racing seasons and a European vice-Champion title. The refined engine features a new, sealed combustion chamber insert with larger surface for improved heat transition to the engine head, a redesigned lightweight engine head with improved cooling, a new carburettor with optimised needles which lead to easier to adjust mixture settings and the K5 also has a more linear power supply. The engine uses a refined manufacturing process and it comes with a DLC diamond coated crankshaft, a high-precision German rear ceramic bearing and a premium Japanese front bearing. The K5 is available as engine only or including muffler and manifold.
