The Max 91HZ-R is developed basing in the 91HZ created expressly for 90 size helicoper models, equipping the brand new O.S. regulator system. The regulator system ensures constantly constant gas supply which is often essential for 3D paths which require replicated energetic mind-set changes and for F3C routes which require serious combination control. Applying this system, fuel tank is pressurized by pressure generatedin the crankcase. The fuel delivered by anxiety is managed by the regulator installed prior to the carburetor, then sent in to the motor.

The latest 61E-R carburetor equips twin needles which allow to change idlling / hovering and high rate combination by themselves.

Much like other 91HZ machines, it features double needles which could adjust hovering and high rate journey independently Regulator is located at a spot by which temperature does not suffer and access is easier
