I finally figured out how to transfer and resize my photos to meet the size for posting. I did a retest today(it is about 20 deg cooler) and found the original out of the package prop was 45.6 oz @ 19.5 amp, the mod prop was 48.6 oz @ 19.03 (all done with the same full charged battery pack today). This is more in line with what I expected. Sorry about the difference in data, when I did the first test and saw the 39 oz thrust number I thought it was fine as it matched up with some earlier test on a APC 10x6 I did over the summer, I was wrong for not doing a second test on the base prop.
Ok, the photo shows the back of the blade hub smoothing, the prop on the bottom is the tip under camber sanded in. Second photo is the Hobby King thrust test stand with amp wire loop (the thrust tester I have only does thrust, I check the amps with a Craftsman clamp meter 82369).
I guess the only true way to see if there is an improvement if to fly it and see how much is pulled from the pack and if the UC tips add some extra pull out of the exits. Hope to get to this next weekend (work getting in the way again).
Best, DennisT
