After reading this post at the beginning of this month, I ordered some of these "magic" props to try on my .25 LAs. I finally got out today. Actually, first time in a year for me to get out flying. When I pulled the prop out of the sleeve, I was skeptical, as the blade width was narrower and the blade profile didn't seem optimal. But try it I did. I was happily surprised with this prop on my Skyray. More pull than the other props I'd tried before. Performed better than the APC 10x4 that was on there, and better than the 9x4 before that. I was never very happy with either the 10x4 or the 9x4. Both just seemed wrong for this particular plane/engine. Glad I ordered three of the 9.625x3.75N props. Now I just have to get good with the plane.
Thanks for the info,
Mark
