Don't listen to whoever told you that George. It is application specific. You design it for what you are doing. Each design has an optimum point and it's worse everywhere else. All you can do is move it around.

I can't give specific advice...precisely because of all the variables. If you were paying me to design one, I would call Craig Catto. ;-)

Monty,

Prop efficiency climbs (so I'm told) until it reaches speed of sound, so I believe some try to take the prop as close to 3,000 rpm as possible, yet some stay a conservative 2,700 rpm, what do you suggest, given all the variables.
