Minn... Thanks for the information.
Well, I stand corrected! I often wondered why, after a hard landing and chipping the tip off of one side of a prop, then flying again, that the plane never seemed to be any different. But, like most other 'sheep' in this hobby, we follow the suggestions given to us by the 'more experienced' pilots out there.
That means that I have thrown away several props that, otherwise would have been just fine. Go figure. Ah well, perhaps I ought to buy some APC stock
