Prop for the YS 63
I like the 14x4W APC on my Laser 3D. 5 pounds 4 oz. It does have a little spool lag but it doesn't bother me... this plane is so predictable. I don't think it's over revving. I like it better than the13x6 APC. I wish I had a bandoleer of other props to try but just can't justify the expense.
