Paul,

You are deeply involved in the prop effort and you must have an opinion on
the propeller design software that is available.

I am trying to make a constant pitch prop similar to that of Nigel Field, Al
Wick and others.

Bates has two programs, one cheaper and simpler, one super duper and
expensive. There are some other free programs on the web. All of them
calculate diameter, pitch and width  of the blades.  Bates programs provide
the airfoil dimensions at different stations, but still you have to rotate
them by the pitch angle. Others program do not do that but scaling an
airfoil up or down is not a real problem. The real question is if the
programs provide good answers providing parameters that are close to
optimum.

I wonder which of the existing programs would you recommended for that task.

I highly recommend Don's software but I have not actually used it :-)
Just attended some of Don's seminars and spoke to him extensively.
He really knows what he is talking about and has a lot of experience.
Perhaps someone else on here has used his software.
