OS Max 55HZ-R Engine (Limited Edition) with Powerboost Pipe 55 II
S$549.30

Availability: Coming Soon

This limited version of the OS Max 55HZ-R is designed for 50 size helicopters for 3D aerobatics. It has DRS (Demand Regulator System) that provides the optimal pressure of the mixture/air regardless of the position of the helicopter during flight. This package includes the Powerboost Pipe 55 II that delivers excellent high performance in the rpm range used regularly in doing maneuvers, while it secures the stability in idling and hovering.

The 40L-R carburetor is equipped with twin needles which enable adjustment of the idling/hovering and high speed mixture independently.

The new regulator systemensures an always steady fuel supply which is required for 3D flights which require repeated vigorous attitude changes as well as mixture control. With this system, the fuel tank is pressurized by pressure generated in the crankcase. The fuel sent by pressure is regulated by the regulator installed just ahead of the carburetor, then sent into the engine.
