prop size for saito 72
#2
I don't have exactly that, but I do have a Sig 4 Star 60 with an OS 70. I like it with an APC 14x4. It's not fast with that prop, but fast enough for me, and the vertical is very good; landings are not floaty at all.

My 4 Star 60 is not a 3D plane, but I like the 14x4 and do not get "floating" on landing that many complain about with that model.
The 13x6 and 14x4 put very similar loads on the engine in the right rpm range. Best to get one of each and try. Based on "puttin around", I'd guess the 14x4, but only your test will tell.

I'd think a 12x8 would work well. I use a 13x6 on my Cub with that engine. It puts along as a Cub should, but it's not fast. I think you'd want a bit more top end speed for a sport plane, especially on windy days.
