RE: Prop for YS1.10
I was running a 14X10 APC on my older YS 91.
When I got the YS110 I moved up to a 15x10APC.
I am shortly going to be trying a 4blade 14.5X11. I'll let you know if it can turn it & how it performs.
I've read posts of people running a 16X8 with good results, but I haven't tried it.
