Okay, that's the compact hub. To go that route with a Comanche 250 you
need an engine counterweight change that I didn't want to mess with. The
3 blade McCauley has worked out for me, I get solid 160kt cruise and better
climb. I've heard that going from 2-3 blade can cost a knot or 2 in cruise
but I didn't see that... I think the new APP cowling helped.
