Prop Selection -APC 17 X 12
 

Running on my OS 1.60 with KS canister MUFFLER (not tuned pipe)...

Those of you using either an APC 17 x 12 Std, or a 17 x 12N, would you share how you arrived at that conclusion?

Acceleration? Quiet? Braking? What props did you compare it TO to arrive at your "this is the "one" decision?
Been doing a lot of prop testing lately, and would like your observations...

I'm using a OS 140 RX and I didn't see any difference in the flight performance between these 2 props. I decided on the 17x12n because it was lighter and I wanted to move the C of G back.

HI Bob,

If you don't mind some extra RPM, I'd suggest the 17 x 10 wide or regular. The first 17 x 10 APC made was a narrow looking prop. They now have a wider one available. This prop will give you smallest gap between low and full throttle. The 17 x 12 "can" give some FAST flying if your not careful. On the Mintor 170, the 17 x 12 gave utterly ridiculous vertical speeds. I went to the 17 x 13 to help smooth things out. On the Mintor 140, I love the 17 x 10 prop. VERY constant speed. Plenty of vertical, very nice horizontal speeds. I checked and there is about 100 rpms difference between the 17 x 10 N and 17 x 10 W. At 8500 rpms, mine sound checked in the 90-91 DB range at the Nats. Enjoy.

PS. The 140 shakes so little, that the new engine mount on your site will probably work VERY well.

My Webra 145 ran a 17x12 at 7800. However I needed more vertical power and have moved to a 16x11 giving 8200 ...not as nice coming down however
