<DIV><FONT face=Arial size=2>In my case, it's a fairly simple problem.
The 1.40L vibrates so much, that the stud unscrews from the head, leaving the
header dangling in space alongside the exhaust port. I have about a foot
of Teflon tubing between the outlet of the header, and the inlet of the Hatori
pipe. I also have their (NMP) header brace in place to try to help
stabilize the header. </FONT></DIV>
<DIV><FONT face=Arial size=2>The engine has already, after about 6 flights,
broken a Johnson Header; that's why I am trying the NMP. I got the last
NMP Central had in stock, and they said that the person who was making them is
not doing so any more. (That's what I was told, anyway.) The
Hatori pipe is sitting on one mount, about halfway back on the pipe, and the
whole outfit is free to move back and forth along with the engine
movement. I had hoped that, with the entire mess moving, it would permit
the stud to stay screwed in the head. I'm worried lest the stud strip
the threads in the head. The instructions say that "some people have had
the header loosen" and to try a certain type of Permatex form-a-gasket
material. I've used this stuff before when I had a racing engine
business, but I certainly never used it in this type of
application.</FONT></DIV>
<DIV><FONT face=Arial size=2>It seems to me that the entire problem is caused
by the excessive engine vibration that the 1.40L is known for.</FONT></DIV>

<P class=MsoNormal><SPAN
style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri','sans-serif'">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: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri','sans-serif'"><o:p> </o:p></SPAN></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri','sans-serif'">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>

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>

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>

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.

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>
