I have YS63. I like 13x6 APC or MA.
With APC 13x4W YS has a little too much rpm and feels like plane fly a little too slow.
14x4W is not spooling fast enough for my taste and I think overheating my YS here at 0ft elevation and over 100degF outside.
So I ended up using any 13x6. Also, I use YS20/20 fuel.
I don't have Saito 82, but people report APC 14x4W is great on this motor.
