Thomas,
You might also want to consider a Prince
propeller. See http://www.princeaircraft.com/
Lonnie Prince is a great guy to work
with and very responsive. I am using one
of his composite P-tip fixed pitch propellers on my Mustang II with a turbo 13B
rotary and it has worked very well for me.
Prince makes a very high quality propeller and he will customize it for
you.

Pitch props.
Actually I would prefer a wood/composite type of prop. I just got
off the phone with Craig Catto and he has agreed to look further into the deal.
He is really a smart guy. Nice to talk with also. Lots of experience there. We
will see what he comes back with. He did confirm my thinking is correct about
having excess power for take off and climb. The idea is to over power the fixed
pitch prop to get it spinning and working. Once you reach those numbers all is
good. I am hoping it can be done.

They still make wood props, too, & they would almost certainly be
able to hit your RPM/HP/speed target if you can give them good numbers on the
HP & real world speed for your airframe. They were able to duplicate the
speed of a Bernie Warnke prop (very, very good prop) on an RV-4 I owned about
10 years ago.

Another
possibility is Senessich (never could spell that), they have a new ground
adjustable prop. Carbon blades aluminum hub, which is supposed to be designed
around RV speed and HP. They are supposed to offer a 2 and 3 blade option. Bill

I’ve been thinking along the same lines. The one
person I’ve heard of often as a potential builder is Craig Catto, www.cattoprops.com
. Last time I looked his props were around $3,000, I think, but I have no
idea if that is current. There is also a new possibility, which is
to have the prop manufactured on a resin printer and then wrap it in carbon
fiber. I’ve done a little research on that front and spoke to a
manufacturer last year at the CAFÉ Electric Flight Symposium (this weekend in Santa Rosa!) who
confirmed that it’s possible and is already being done for military drones.
Please post your findings!
Thanks,
Mike

I am curious what
you folks might recommend for a fixed pitch prop builder for my project. I will
have a lot of excess power and do not think it would be as difficult to get an
acceptable level of performance with a lot less money and simplicity. Your
thoughts
