I have used the old Rev Up 10-6 EWs in the past with much success. Unfortunately, they are not readily available anymore!
Any ideas as what prop would be good for the McCoy 40? Open to any and all recommendations!
TIA!

There is an old Hobby Shop in Hartford, it's not frequented much anymore. Bad location, lots of trouble. I will go there this week and see what they have? Actually it is in someones basement, not a retail store. I will let you know if I find what you want? I want to go there because rumor has it he has two "DROOL" Morton M-5's for sale? How can I pass this visit up? LOL LOL LOL

I always liked to use 11-6 SuperM's on McCoy .40's.

You might look at the new 10-6 and 11-6 props that Eric (RSM) is importing. I just got a few, and they appear to be excellent, although I hanen't used either size yet.
Also, check your email . . .

Try the new RSM props. They make "10-6" and "11-6" so far. They're actually about 5.5" pitch, have .020" undercamber and are ready to run, slick, balanced...wood! I'd try the 11-6 and trim it down if needed. I'd also look at Zinger's website. They make some XW's that you don't see in the LHS...direct order or special order. I got some 11-6XW's through my LHS. They're actually better shaped than the usual sizes, too. No, really! H^^ Steve

Thanks, guys! I haven't dabbled too much in wood props for a long time. Mainly because I have a bunch of the old ones and a whole lot of 12-5 Rev Ups, which as Ralph can vouch for, make all sizes down to about 9 1/2". But I would like to know what "new" props, or ones I haven't tried, are available. Thanks for the information! I will check out the RSM props, and see about the XW Zingers. I now remember having a 10-6 XW Zinger once, somewhere!
Having only used the 10-6 XW Rev Ups on the McCoys, I really don't know what they will turn........and they have been REAL happy on those XWs! **) And the Rev Up 10-6XW were seldom a "6" on the Prather.
Keep the suggestions coming!

Bill, You might want to look at the Zinger Pros. or if your really adventurous then go for the thunder Tigre 10.5/5 or the 11.5/4 nylon type prop. These props work extremely well are non flexable, balanced have a large blade shape, are really well made and pull like crazy. Also they seem to make your motor run a little quieter. Oh and they are really reasonable in price too.
You can buy them online at the Ace site.

I ran mine on APC 11 x 5's.

Check out "www.Thudertiger4U.com", their prop prices are very good. $1.89 for the 10-6, $9.89 for 6. The also list the TT engines for very good prices.

The Bolly 11x6 ran great on mine.

FWIW: The McCoy 40's didn't like to be loaded with a big prop. The larger props always made to 4-2-4 break sluggish and weak. My experience with the Mc 40's is they worked best with 10 X 6 Super Maples or the Rev-Up 10 X 6 W and would tolerate the Grish 9 X 6 silver three blades. The old TF Power Prop 11 X 5 could be used it the diameter was cut down to 10-1/2" but that was about it. On a reasonable weight model they were pretty good with a slight advantage over the Fox's with about 200 rpm at the most.

Ed Southwick did pretty heckity darn well with those three blade Grish 9-6's on those beautiful running McCoy 40's!!! Too many flyers give up on those old Grish tri-bladers because of a little bit of tip flutter and vibration...but if a little care is taken to balance those old props....they worked beautifully and actually seemed to help some of those older heavier models..."pull through the square corners at tad better. Also seem to retain more consistant speed through the square 8's with virtually no slowing down of the model. My old OS 35's LOVED THOSE OLD 3 BLADERS!

HI Bill
