Rock: I've never tried the three blade props. I've seen some people here on RCU (via pictures posted) using them but few at the field. The Pattern folks seem to use them a lot, but for some strange reason, they don't recommend them to those of us that are working our way up in experience levels.

I have a Goldberg Progege with the OS 75 AX engine and use the 14-6 prop I mentioned above and it seems to give me good, consistent performance with that 'unliminted vertical' we all seem to strive. But it does climb vertically with out 'effort' with that prop. I just wonder how it will do with the three blade you recommend.

I may give that a try and see. Can't hurt, that's for sure.
