style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">With the 18.1x10.1
and YS 160 launching around 8100, the speed changes of the plane nearly follow
the throttle stick movement. At full tilt, the plan can still accelerate
away from you, however, at ¼, 1/3, 1/2, ¾ stick positions, the plane changes
speed as you move the stick. Very nice. I tried the DL 15.75x10 3
blade this weekend on the YS 160. This prop is very quiet, the overall
speed was a tad less than the 18.1x10.1., At the top end, it did not
accelerate away from you, and overall, it was a bit easier to shape the
pattern. Plane speed definitely changes with stick position. With
the 18.1 I find myself changing power settings on uplines and such – requires
quite a bit of throttle stick work to not “explode” through maneuvers.
With the 3 Blade, it was easier to hit a consistent pace.

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I am Mike Harrison, I worked
with APC to develop these props. Let me tell you the goal of the prop
design. It is to fly at a moderate to slow constant speed under the
noise limit but with good pulling performance. Therefore, regarding
the rpm, the 8000 is about ideal for that prop, turn it much more and you
will be above the noise limit. </SPAN></FONT><FONT

<DIV>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I find it interesting that you
determine whether a prop is adequate by first tacking it. I would
think you would fly it first to see if it was adequate. I would
encourage you to do that first. The OS 140 turns it about the same and
it flies very well. </SPAN></FONT><FONT face="Times New Roman"><SPAN
