70in X 86
My original Aymar Demuth was 68 X 81 and the Sterba is a 70 X 86.
I got slightly different numbers from the couple different manufacturers I discussed it with also. I guess how they measure it, where, what type of shape the prop has all makes a difference. I did measure the two props at a couple points on the outer half of the blade and they were within 1 degree of each other . . . as accurate as my guage was anyway.
The Sterba has a much thicker root with a narrower tip. The Aymar Demuth was a fairly thin blade, especially at the root and wider all the way to the tip.
I posted a year ago about the change and what numbers I was getting.. . . however the main difference ended up being the airfilter I used as a temp replacement until my new K&N showed up.
I believe my static rpm now is somewhere around 2350 to 2400 rpm, but I've only done that a couple of times last year. It stays in that ballpark on climbout and wont get to 2500 rpm and above until I start to level off.
