INTRODUCTION
Standard accessories
Glow Plug No.8
Check Valve
The MAX- 55HZ-R has been developed based
on the 55HZ designed expressly for 50 size
helicopter models, and equipped with the
new O.S. regulator system.
The regulator system ensures 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. The 40L-R carburetor is equipped
with twin needles which enable adjustment
of the idling/hovering and high speed
mixture independently. The cover plate has
a cell to accept a sensor designed to install
in the cover plate from the Futaba GY-701
Governor.
As delivered, the engine has the
carburetor lightly fit into the intake.
Secure it changing the angle according
to the model.
