Produktinformasjon
91HZ har nå fått en ny utgave med høyere ytelse og nytt regulatorsystem. Tanken får trykk fra baklokket og forgasseren har fått en ny regulator som gir jevnere trykk hele flighten og renere fuel. Leveres uten potte.
Based on the multi-time FAI world champion 91HZ heli engines, O.S. is taking their new 91HZ-R to even higher levels of performance; thanks to the new on demand regulator system. Designed specifically for this engine, this system guarantees the steady fuel supply, needed for the most-demanding of 3D flights with constant, vigorous attitude and throttle changes. The 91HZ-R also performs well as an F3C powerhouse providing a steady, smooth run and exacting mixture controls.
Unlike a pump or muffler pressure the fuel arrives at the regulator under a constant pressure. This ensures the engine will run exactly the same throughout the entire tank- from full to empty. Additionally, this regulator has been designed so that the mounting position of the system is perfectly in line with the carburetor resulting in consistent engine operation in all attitudes of the model.
Rest assured, 91HZ-R will never be lacking in fuel or lagging in performance!
