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.
