Default RE: OS .55AX engine break-in and usage
For a more quantitative answer, my 46AX was turning an 11x5 prop during break in at 11,500 rpm and got up to 12000. I tried a 12x5 and the rpm dropped back down to 11000. I switched back to the 11x5 for a few more gallons, and now the 12x5 spins up to 12,300rpm.
