Frequently Asked Questions
What is a flyball speed governor used for?
▾
A flyball speed governor regulates the rotational speed of a steam engine by adjusting throttle position based on centrifugal force, maintaining consistent performance under changing loads in model and full-scale engines.
Does the Microcosm P60 come with mounting hardware?
▾
No, the Microcosm P60 does not include mounting hardware. It features a 1/4-40 TPI thread for attachment, but users must supply compatible fasteners or fittings for installation.
How do you adjust the speed with this governor?
▾
Speed is adjusted by changing the spring pressure on the governor mechanism. Tightening or loosening the spring alters the RPM at which the flyballs engage, controlling engine speed.
