MOTOR OS 55HZ-R 40L-R HELICOPTERO 15650

Description:

• The latest engine in the 600/50 helicopter class borrows much of its technology from the fabulous Max 91HZ-R, to provide class leading power under the most demanding of 3D manouevres.
  
  
• The latest DRS system (Demand Regulator System) uses a crankcase pressure tap-off to pressurise the fuel tank via a one way valve. The pressurised fuel is then carfully regulated at the carburettor to provide the optimum mixture no matter what demands are placed on it. This is done by using the negative pressure in the carburettor venturi as part of the regulation system.
  
  
• The carburettor itself has three mixture controls for low/mid and high speed settings. Once set for the fuel demands of your model/type of fuel and muffler, there is rarely any need to change those settings again.
  
• The main mechanics of the engine itself are the same as the regulat Max 55HZ.

• DRS system delivers fuel to the regulator under constant pressure for precise fuel delivery throughout the entire tank from full to empty
• Same mounting bolt pattern as the OS 50SX-H Hyper
• Dual needle 40L-R carburetor allows independent adjustment of idling, hovering and high speed with four arm throttle lever for use with a variety of servo brands
• HZ Hyper low profile six fin cylinder head
