Cheech, thanks, I will go there and look for props. Which YS120 do you have? I have the YS120 that came after the YS120AC. I had read that the highest thrust prop for that engine (any YS120 actually) is the Zinger 16x6. How well does your 120 pull that apc17x6? I know the 17x6 is the best prop for Saito150/180.
My YS is the same as yours, I believe. After the air chamber but not the current engine. It just says
120 F on it. I liked the
17x6 just great, but it was
NOT the best hovering prop actually. This prop and engine is on a
big profile fun fly plane. I started wth a
16x10 on it when first bench running the engine. My buddy and I had each just rebuilt a pair of these 120's. I have tried the
16x10, the 16x8 and the 17x6 . As far as best prop in the powerband at hover, we are all in agreement that the 16x10 is the most cointrollable. We're talking about subtle differences, though, an I am being nit-picky.
I lost the 17x6 prop to a
lean run caused by a teeny fuel line leak. The YS coughed off the spinner, nuts, prop, washer, etc... The prop was damaged. I then went back down to the 16x8. Great thrust, but wrong RPM when in the hover zone. I am flying the
16x10 again this afternoon. Even though it seems wrong, it IS the best performer for me and I will stick with it.
