Hey Guys,
just wondering if anyone has switched form a borer to a Catto on a floatplane?
Catto suggests a 84X36 for a 150hp super cub on floats and a 84X37 for 160hp,
the also said that some guys run the 36 with 160 hp
any info would be appreciated.
Thanks
Is your cub certified or experimental?

Except that it's written right into many TCDS' in many of these older aircraft. I say as little to a fed as I possibly can.Had a quick winter safety visit from the FAA last week. Very cordial and informative. Discussed controlled flight into terrain and carbon monoxide. No other problems.
I mentioned that at one time I had considered installing a wood/composite Catto or similar via a coordinated Field Approval, but had discarded the idea as I wasn't sure the work and expense were worth the potential results. Another local FSDO rep was supportive and offered help with the paperwork but in the end I put the project on hold.
The ramp folks noted the Catto wasn't approved on certified planes like my Taylorcraft. I agreed and then mentioned they were seen from time to time and if the aircraft they were on were experimental? There wasn't much else to say about that from them or me.
So unless experimental some form of approval is required. That's not headline news. And citing CAR 4 certified aircraft as eligible for wood props w/o approval only applies to what that reg calls "light aircraft"....those under 1000# GW.

Thanks GAP, That is encouraging, I take that response as "let's run it through the system, it is worth a try". From my previous experience with the Alaska FAA, I take that as an almost YES.The quote from my contact at the FSDO:
"Unfortunately, as the Cato propeller is not a wooden propeller of "conventional type" given the fiberglass wrap, I and the gentleman I spoke to within our Technical Standards Branch feel it would not qualify as a minor change. Given that this would be considered a major change to type design, I would like to encourage you to submit for a field approval so that an engineering evaluation may be made by the Administrator."

If you could get a section of a blade to show how much is wood and how much is the "fabric" cover along with a conventional wood prop with it's fabric tip cover??????? It's a place to start. Assuming you are silver tonged and can carry on an intellectual friendly discussion with Mr. FAA, progress can be made. It's amazing how well this approach works.
Hey cub12, Im looking for a catto 84x37, Im in NS Canada and wondering if you know of a canadian dealer
As far as i know i was the only one dealing in Canada, Lately i have just been sending people directly to Catto. but feel free to give me a call if there is something you have questions about, 40m posted my# above. They are a great prop, stand up very well,are extremely smooth and are nice and light.

It would be great to save 30-pounds up front. I wouldn't want to do so at the expense of performance, though.
What could I get on the used market for my 82/44 Borer in decent shape?
