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.

apc 17/4w.... but they don't make it yet...to bad....[:o]


try apc 16/4w or 16/6....don't go over a 6 pitch

I like the APC 16-6 on my saito 120

About what I had guessed:)

Thanks alot.

I run a 16x6 MA on my OS 1.20III pump

RE: 120 4 stroke prop ??
 

APC 16x4W

OS 120III

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

RE: 120 4 stroke prop ??
 

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

Never checked it...just put it on and it worked.

YS 1.20 AC, APC 17x6, pulls 8.5lb SIG 3D Mayhem like a locomotive and thats at 5500 ft elevation.

he said it was an OS not a ys...big difference


17/6 apc is too much prop for os 120

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

RE: 120 4 stroke prop ??
 

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 [:o]

RE: 120 4 stroke prop ??
 

you said it brother

RE: 120 4 stroke prop ??
 

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
