<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The NMP header was a really good header for the application.
When we were using Teflon tubing to connect the header to the pipe it was
excellent. The problem was Hatori went to the newer style pipes that the header
slides inside of the neck of the pipe with the o-ring. The aluminum tubing used
on the NMP header was not as bullet proof in this application. Remember the Teflon
when hot would flex. Now the header and the pipe are attached to each other.
The header slides inside the pipe and the result is there is still movement but
the stress on the thin wall aluminum piping is higher. Breaking, and the header
would get a grove worn in it. Actually the o-ring would pinch the aluminum
tubing to a smaller diameter and the header-pipe combo would leak. The added
stress of vibration and the direct connection many folks would break the header
tubing.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The new header is similar to the Hatori in terms of connection
to the pipe. So that swedging ( shrinking of the dia at the o-ring) problem
and the leaking should be solved. In my setup its working well on the
proto-type headers. Next issue is the tubing being stronger to take the stress of
the direct connection. The solution is kind of unique and is working well. Some
more testing and maybe a few tweaks and its going to be a very good replacement
for the Hatori 822 and 823.<o:p></o:p></span></p>

color:#1F497D'>I don’t believe there is such a prop made as the 18.1-11
Narrow. It doesn’t exist. I may be wrong but I have been involved with
running and testing the APC props in the 18.1 series and WPN series.
There is a prop that is designated as just 18-11 and this has a narrower
blade than the 18.1-11. The 18.1 series of props have a very wide blade.
The 18-11 is more like a 17-13 or 17-12 in terms of blade shape but its 18in
dia and 11 pitch.<o:p></o:p></span></p>

color:#1F497D'>I know there is a 16.5-12 I just pulled one out in my
box-o-props and it has a profile like a narrow prop very similar to the
17-10N…however it doesn’t have the designation as 16.5-12 narrow.
It’s just called the 16.5-12. If you handed it to me with the name
scratched off and said it was a 16.5-12 I would have said it was a Narrow.
Same goes for the 18-11 regular it’s a narrow essentially as well.<o:p></o:p></span></p>

color:#1F497D'>I don’t know for sure why the “W” designation
or the “N” for narrow is left off of some props and added to
others. I think it has a lot to do with the equations and program that is used
to create the prop profile. <o:p></o:p></span></p>

color:#1F497D'>To sum up the props APC has the prop if it is or has been
produced. I don’t think Fred throws any of the molds away. So if a
prop was produced at one time it might be possible with some convincing to get
some of them produced again. I have been to the factory where the props are
produced. It amazing how they are produced, and the quantity and quality of
props produced for a given size.<o:p></o:p></span></p>
