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 Jepson

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,

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
