Default 120 4 stroke prop ??

Hi all

I have a OS 120 pump 3, what prop would you recommend for prop hanging, the plane is a YT International Adrenalin.

Thanks.

16x4 sounds a little lite, what's the peak RPM.

I agree on the 16x4, my YS AC turns a 16x8 at 9500, anything less would shred it....

I'd like to find a good fun-fly style prop for my YS, so I can stuff it into a Funtana .90

Outssider

Ya, yer right, big difference. But I was talking to puffstatler, he has a YS

Dokey-as far as the OS 1.20, go with a 16x4W if it can handle it, my YS .91 can!

I love power

Im just kiding around, but seriously try the APC 16x4W, I guarantee you'll love it

what we need is for APC to come out with a 17/4W and 18/4W

that are identical in shape (except larger) to their 16/4W


NOT LIKE THEIR 18/6W....way to massive []

I have tried the 16-4 W on my 120 and it doesnt pull out quite as well as the 16-6 APC IMO . a 4 pitch is great for a 2 stroke or a small 4 stroke but I feel the 6 pitch is better for the larger 4 strokes. If properly propped for thrust they should not be turning over 9500 rpm anyway
