HPI have released their Nitro Star F3.5 Pro engine, which has been developed especially for off road racing. The HPI engraved oversized cooling head has been drilled and lowered over the crankcase for maximum heat dissipation and keep the weight as low as possible, fitting on top of a separate Turbo combustion chamber. A finned black-coated crankcase design not only adds strength and rigidity but will also help cool the engine. The F3.5 Pro is a 5 port 3.49cc ABC engine and has been optimised for performance and durability without compromising on run time. Tested with the HB and HPI Racing teams with great success this is an engine that can win at the highest level at a price that’s ultra competitive.
