HPI F3.5 Pro Engine

The HPI F3.5 Pro engine has been developed especially for off road racing.

The HPI engraved oversized cooling head not only looks great but has been has been drilled and lowered over the crankcase for maximum heat dissipation and keep that all important C of G as low as possible. It fits 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.

Tested with the HB and HPI Racing teams with great success (UK National A Finalist already) the F3.5 Pro is an engine that can win at the highest level at a price that\'s ultra competitive.
