I agree with most people here, I dont own a Rotorway and probably never will, although I do think that the shaft breakages reported were either the factory prior to modifying to 35mm or with belt drive, Im lead to believe that there hasnt been a 35mm shaft breakage whilst running standard factory chain drive. ( I do stand to be corrected here )
Suffice to say, working on a machine, for 2 hours to fly 1 hour, don't do much for me
