Hi all,
Just down from the modeling room, where I have been running my OS 32 with no fly wheel.
Unfortunately it's raining cats and dogs, and blowing a gale, so I had to do this in doors, as I have no shed.
It started as easily as usual, but with the exhaust and fly wheel removed was out of tune. Because of the noise smell and smoke, I did not have time to re tune it, but from fast tickover and upwards, it ran OK.
I also have a Thunder Tiger Out board motor, and the fly wheel on that is tiny and made of alloy, so virtually no fly wheel action. That also runs and ticks over with no trouble.
I wonder with regard to an aero engine stopping when the prop falls of, wether this could be because with the prop on, the throttle will be open wider to keep the motor running. So when it falls off the loading changes, as will the throttle setting to keep the revs the same. With no resistance, it would require a lower throttle setting. If you see what I mean.
I wait with interest.
Bob
