RE: Prop for OS 46 AX
11x5 has been ok on all those engines at our field. A number of fliers have had better luck with 11x6s.
10x6 used to be the accepted standard for 35s. All the guys who've run them at our field on the 46AX have changed to larger props. Well, one guy still is running a 10x6 but he loves speed and screaming engines. I've tried to talk him into trying a 10x7 or 10x8 but he hasn't so far.
