My favorite of the props tested, is the
APC 13x8. It gave me good thrust and
excellent throttle-up transition. My 95AX has been in two airplanes so far. It was first put into an R3 Gee Bee, then later moved to an old Great Planes FUN-ONE.
I also installed a Performance Specialties "ULTRA THRUST" on my AX. I plan on testing the props again to see which one's do best with this tuned muffler.
