Like the title says, I need recomendations on a good 3D prop for the OS .91FX. It's going on a .60 size profile, I prefer to run wood or APC props, and 15% nitro.

APC 15x4W. That's what I've been using on my H9 Twist 60 and it works for me.

Same here.
I am running APC 15x4W on a 91SX-H in my Funtana 90

Thanks, I'll try that.
