News: NITRO STAR F3.5 Pro 2013 Engine

The amazing F3.5 Pro racing engine has been redesigned for 2013 to make it faster, more powerful and better than ever! With all-new parts including the crank case, piston and liner, fuel intake valve and more, it's been tweaked for maximum performance and rock-solid action.

Designed purely for off-road racing, it's the perfect companion for HB and HPI buggies and truggies, and it's an easy drop-in fit for all other brands as well. A huge laser-engraved aluminium cooling head is cut and drilled to lower weight while providing maximum heat dissipation at high temperatures. The multi-finned crank case features a turbo combustion chamber and is coated black for ultimate cooling.

The new-for-2013 F3.5 Pro engine is a 3-port 3.48cc ABC engine that is optimised for performance and durability without sacrificing a second of race-leading lap time. It has been fully tested by HB and HPI factory team drivers with fantastic success and is a solid power unit that can win at the highest levels of competition, with a price that is just as hard to beat.
