As I walk through all the issues with this restoration of a rusty old plane the latest is my prop failed certification due to some surface corrosion. Although disappointed I guess I should not be surprised as it has been neglected for the last 25yrs. Downside it’s more $$ into the project, upside I get a new prop.
This is an import into Canada project so I have to cross my t’s and dot my i’s thus I need to be compliant as much as I can be with a plane built in 1946. The aircraft had an engine upgrade to a C-90/12 back in the 60’s using what appeared to be a 337 which does not work for me so I purchased the Babcock STC to get the paper to line up. In that STC it specifies either a McCauley 1A90 or 1B90 or wood prop. The aircraft will be based at 3500ft ASL with generally cool temps. So my long winded question is which direction should I go?
Keeping in mind this is a J3 Cub and it’s purpose in life is to absorb all my spare cash, buzz around on nice days, look pretty and have fun, I am kicking around the idea of going back to wood…knowing that there are plenty of opinions out there is there real practical reason why I should go one way or the other?
