Re: prop sharpining
I am totally convinced that a sharp leading edge on a prop translates to improved performance. BTDT
Know not why it would affect any of the other prop parameters.
As stated balance is important. How much, who knows, only running would answer that.
Prop shops can do it and check balance as stated.
If the prop is a looser and you have nothing to loose, you might go ahead and do it yourself remembering to keep the amount of material you remove from each blade equal.
I have a Hustler alum and I thought about sharpening the blades on it just to steadfastly prove the point that sharper blades work. Like take data on the prop, take it home and sharpen it, and go back and take data again.
