Alpha gear ratio

[Donziweasel]

I ordered a new 17 pitch Turbo 1 prop and Bennett Trim Tabs. Just out of curiosity, what would replacing my 1.47 gear in my alpha to a 1.62 to the RPM's? 200 more is what I was told. Thanks everyone for the advise in setting up my 16 at 6000ft.

at sea level , going from a 1.8 to a 1.62 was about 4 - 500 rpm . i would think it is about the same ...
