Like Gabe said, to me and you it is very hard to tell that a prop has been blue printed. You are better off with a known good prop to start out with. Most of the time, once one has been reworked you take something away from that prop. People that know what they are doing can some times make one run a little better than a prop that is brand new by balancing the baldes or by adding or taking away pitch and cup. Lots of work, time and effort goes in to this though and not everybody cam make this happen. Sounds like Gabe is getting a pretty good handle on all of this. Have noticed a difference in his words and his knowledge sense first coming to this board. Good LuckJoey
