Never EVER use any kind of metal prop on a pusher. They don't have the
fatigue resistance that wood and composite props have, so they cannot
thrash through the dirty air in the wake for long before they start
breaking blades. There are some composite CS props.
The conventional wisdom since the 70s .... Jim S.

I would be very interested in talking or e-mail with anyone out there
on the list that is using or has experience with a constant speed,
hydraulic, metal Hartzell prop. I'm looking at a prop for my pusher
(Velocity) using a 20B and Tracy's RD-1 PSRU. Looking for potential
problems using metal prop and hooking up hydraulic governor, etc.
