55HZ Limited Edition Heli Engine with PowerBoost Pipe

55HZ Limited Edition Heli Engine with PowerBoost Pipe

The O. S. 55HZ Limited Edition retains all the performance features of the 55HZ-H Hyper – with a wicked new look as well!  This special version engine is all black with “2010 Heli Jamboree Edition” laser etched on the engine and pipe.  The 55HZ Limited Edition features a dual needle 40L carburetor with four-arm throttle lever and offers the power of a .60 with the same mounting pattern and silencer size as the 50SX-H Hyper engine.  The compact PowerBoost Pipe improves efficiency and power for idling, hovering and performing high-rpm maneuvers.  Because this engine is “limited”, only 250 will be produced – with each engine and pipe being numbered to match each other at the factory.  Power, performance, reliability and sharp looks – all available in the O.S. 55HZ Limited Edition!
