I didn't want to post anything about thrust numbers because I don't have a fish scale and rope to actually test the props. I just have a tach to report RPM.

I do concur with poco242 on the APC props. They might perform well in the smaller sizes, but the big ones just turn a lot of RPM and make noise. They don't actually pull worth a hoot. I can tell by the way my plane flies. My 80" Patty will hover easily at about 5/8 throttle with an NX or MSC 22-10. With the APC prop--RPM is up by 200-300, but it won't even hover at full throttle. Lots of noise--not much go.
