Default Wood prop

I'm thinking it's time to replace my wood Culver prop on my -4. I'd like to put on a 2 blade Catto, but with a nickel leading edge and new spinner they are really getting pricey! (almost $4000 !)
Would like to hear any suggestions on favorite wood props for the -4 !

Might want to check with Ed Sterba in Ocala, FL. I just bought a prop for a Pietenpol and it was quite reasonable.

Does that price include the spacer, bolts, backplate, spinner and prop? I was thinking of trying a 3 blade, but not at those prices.

There is always Whirlwind or Sensenich ground adjustable props too:

Default Sterba

I have a Sterba on my -4.. I bought it used from a -6 being parted out,and re-finished it. I am running 160hp, and this prop is smooth and a great climb/acro prop, but my top end suffers (I think) because I can still easily redline past 2700 RPM at 8-10K. I cruise at 150-155kts while turning about 2550 RPM, so I live with that. Cant remember my pitch/diameter, but I'm thinking 68"dia. The prop is beautiful, and it has the urethane leading edges that are really nice for erosion protection. I have 250 hrs. behind mine and doubt I will look at replacing it any time soon...lots of bang for the buck.

Default Wood prop

The Sterba sounds nice, especially with that Urethane leading edge... will look into that.
Thanks!

Also, Sterba will repitch the prop free of charge until you're happy. Obviously, easier to go from coarse to fine pitch.

you should also check out Performance Propellers. Frank makes a really nice prop for the RV4, two or three bladed. www.performancepropellersusa.com

Sterba is the best cost benefit

What, do they give them things away? A whirlwind or catto including spinner, backplate and nickel plated leading edge are only a couple, three grand. And by today's standards the sterba is one ugly propeller.

I needed a prop for my -4 and it turned out that Ed Sturba's shop was 20 min from where my folks stay in FL for the winter. So my Dad called him up and dropped by. He expected to find a high tech mfg facility with a cnc router or a fancy duplicator. Nope. The guy has a few templates hanging on the wall and an angle grinder! He's old school. But he's built 100s of props and the one he built for me looks very nice. He knows what works for RVs. I don't think you can find ANY other prop for less than twice what he charges. My Dad said he was a really nice guy too.

I am still a year from flying so I can't tell you how mine works but there are lots of others who can.
