Hello,

I was just wanting to know what some of you guys are running for prop size on your 91 fz's. I am going to stick with a 3 blade and have been looking at graupner props. 14x7x3 is my primary choice. Anyone else second that opinion or should I go with a 15x8? I'll tach my engine after getting the prop, but I'd like to at least get close the first time to prevent buying a bunch of props. Thanks in advance.

I have a ys120 that I run a 15x8 two blade and a 14x7 three blade. On my twin Magnum 90s I run 12x8 three blades.

i run gruptner 14/7.5 two blade on my YS 91 ac turnning 9800 rpms on the ground. I'd guess the FZ91 will turn the same prop.so that means your looking at a 13/8 as a 3 blade.
