Starting to look for a prop for my exp Pitts S1S project.
I’d like to go composite
Stock 180 hp IO 360 1/2” flange lugs

I’ve been told these work well:
Catto 74/60
Prince 76/54

Open to suggestions

thanks,
Doug

I have traditional Aluminum Sensenich 76 x 56 from my old experimental S1S that was parted out. It has about 530 hours on it since new. Never reworked.

Those Catto numbers are definitely not for a 3-blade that will work on an S-1. Craig builds 3-blades standard for 360s and you'd want something more like 72-56 max for a 180 without performance mods. I preferred his 54 on mine for optimal acro performance. Not sure what a comparably performing 2-blade would be, diameter and pitch wise. Not sure I've seen a 2-blade Catto on a 360, not that he couldn't build one for you.

I've mostly seen 3-blade props lately from Catto, but Craig has done lots of 2-blade props for 360's. Many of the guys I race with at Reno run 2 blade Catto props on their pumped up 360's.

We have had good results from Performance Propeller USA out of Texas, Frank Johnson, you won't find a more honest smart guy to do business with.
i think the company has it's roots in Bernie Warnke since the 50 or so laminations give semi-constant speed twist.

Cool - 2-blades are definitely uncommon for the acro Pitts folks. 3 blades flex a little less for snaps and tumbly stuff and definitely make less noise at 3400 RPM. :)

I think Craig started doing a lot of 3-blade props after he got the CNC mill in the shop to shape the props a lot more easily and accurately. I only know of a couple of 3-blade props he did before then.

Here is some more history of Performance Propellers;
Bernie Warneke "almost constant speed" prop. He made laminated wooden props; most have 5-10 layers. His had 30-35 layers, flexing under load to emulate a constant speed prop.
Bernie Warnke passed away some time ago. Margie Warnke (Bernie's Daughter) made props for a few years following Bernie's passing, but has since moved on to other endeavors. They used 1/8" laminate wood cores for their props. Clarke Lydick (Performance Propellers) learned the trade from Bernie as well while he was Bernie's son-in law and made a very similar prop, but eventually sold his business. I've never seen anything from the company since it was sold.

Just sent a PM to you, I might be in the market for FWF for my project. I'm looking at a 200HP IO360 which might turn it better

I have a 76x58 Bernie Warnke Wooden Propeller on my Pitts S1S stock 180hp and it will be for sale as soon as I get the 3 blade Catto I've ordered , if you are interested.
I guess I'll get it by the end of the month, hopefully.
