Wow that’s a pretty nice prop! 16 pounds lighter than a Borer.
https://www.wagaero.com/restoration/decals/propeller-decals.htmlI have the 82-44 and like it but would really like to put the Catto on. About 14lbs lighter and a nickel leading edge. My borer leading edge takes a beating. I’ve talked with Catto several times and they keep saying they’re getting it certified but I’m thinking it’s not going to happen.
Catto has built lots of props for a lot of happy customers without any FAA oversight and involvement. He apparently is very busy operating in the manner which he has been. Why should he let the FAA's nose under his tent? I don't blame him for building experimental only props. A comfortable low key living is more important than a big government regulated business. While every one wants to earn a lot more $$$, at some point more doesn't necessarily mean a more comfortable life....There are now thousands of Catto props out there; that have more than proven themselves to be certified airworthy for decades. That really is NOT up
for debate at this point. It's purely political
BS.
Eastern PA. What is typical ROC for a strait SC?
I’m really just trying to learn. I like the greatest ROC as I can reasonably achieve.
I understand that point and wouldn't disagree.Catto has built lots of props for a lot of happy customers without any FAA oversight and involvement.

Perhaps since 2013 he changed his mind? In my reading of the certification requirements, it certainly doesn't appear to be very difficult to accomplish. Particularly for a wood core prop. Maybe he had a chat with his insurance agent?I understand that point and wouldn't disagree.
I just would like an honest/direct answer because in person across a picnic table at the 2013 New Holstein Pig Roast, Craig told me they were working on it and it was two, maybe three years away.
The good news in now there are several certified alternates really in the works.
I should have noted that since then I and others have called and stopped in their booth at OSH but I gave up 3 years ago.Perhaps since 2013 he changed his mind?

Getting anything accomplished with the FAA is difficult-- just ask Boeing re 737 Max.
Try doing something simple like just getting a replacement airworthiness certificate sometime from a less-than-helpful FSDO rep,
maybe it'll give you a different perspective.
Somebody I know watched Bushwheel Bill's video about the QMI hockey-stick-repair kit,
"wow, two thousand bucks seems like a lot".
Considering the horror stories I've heard from people trying to get an STC or any other kind of FAA multiple-airplane approval,
or even just a one-time field approval, $2K sounds very reasonable.
Is there an 84” McCauley that bolts on a -320?Anyone running a 84/43 Borer ?? on a 150?? Whats it like? Is this too much. Whats involved in cutting down to 82.
The 1A175GM which is the "Borer" prop, is approved by the Type Certificate P-857 on the 0-320 series up to 160 hp at a diameter of 78"-82".Is there an 84” McCauley that bolts on a -320?

Why would you want more than 82"? That does a good job.
Kevin, I've heard this talk too. They may use what they wish, I tend to look at the type certificate and found some diameter vibration limitations with that prop which suggest it is not a good idea. Perhaps it is just a matter of what official testing was done?I’ve heard guys talk about Pawnee props on cubs but not an 84” Borer.
Hey guys,
I need an education on borer props and the benefits on a Pa-18-150. Is there a big ROC increase? What are measurable performance benefits?
I know nothing about them. I’m also curious as to the prop clearance issues as i understand owners will add gear leg extensions or larger tires for prop clearance. And is it all worth it for a grass strip flyer!
Thank you I appreciate it!
