The regulator system ensures constantly constant gas supply which can be necessary for 3D routes which need duplicated vigorous mindset changes and for F3C flights which require serious mixture control. Using this system, fuel tank is pressurized by pressure generatedin the crankcase. The fuel sent by stress is managed by the regulator installed prior to the carburetor, then sent in to the motor.
