XRD have introduced the new F.T. Line ATOMIC .21 nitro engine. The 3,5cc power plant comes with a completely redesigned sleeve and updated ports on the crankcase. The new head is machined to sit lower on the crankcase creating a “Low Centre of Gravity” effect, and the carburettor features new needles with a redesigned shape so to improve the mixture passage. As of every F.T. Line engine, the unit comes hand checked with a certificate of authenticity.
