Guy's I wasn't looking to publish any finding's,lol, just curious as to the minute difference in similar props. Xoar 18x8 versus Bold 18x8. Those two have given me the most noteable difference in flight as of late. The Xoar seem's to do better at lower rpm's and fall off at the upper, the bold seem's to be the opposite. This is just my interpretation of how it feel's in flight. All I am looking to see in testing is the difference in pull of the two prop's thru the rpm range of 4000-7000.
