waterboy,

That would be cool if you can give numbers on that Ed Skorepa prop. I have never heard of that one. Your fish scale method is about as good as anything I would think.

jstanton,

I knew that the APC would spin faster, but according to what Scott said, the Xoar spun slower but had more pull, but 18lbs of thrust on a 12lb airplane is not too bad at all.

kweasel,

Yeah, the low pitch props are definently for slow flying. If I knew that it would work I would switch to something like a 22X6 or X8, just so that I could more airflow over the control surface and super slow speeds. I just do not think that the 40cc could handle a 22" prop.

the wasp,

I have never really been a fan of the Zinger props. Well not in my smaller glow anyway. It seems to fly my plane pretty good so far though, well compaired the the Top Flite anyway I will have a real prop in a few days with any luck.

As soon as my Xoar get here, I will run each prop and see what the thrust is and post images of what the scales show for each one. That will get some real work numbers out there for those like me who cannot make a final decision without real data. Must be all these years woking around engineers!!

Thanks for all the input guys.
