  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.

   

  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.

   

  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. 

   

  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.

   

  You may not be asking for it by the proper name/designation..the 16.5-12 (is actually like a narrow) and the 18-11 is like a narrow version of the 18.1-11

   

  As for Headers...the new header is in testing and is performing well. The jury is still out, we are working hard to insure the bugs are worked out. Right things are going well and real progress has been made in the last couple months. It will be sooner rather than later from the looks of things on the new headers.

   

  I hope this helps answer the questions

       Hello all! I'm looking for APC 18.1x11 narrow, and 16.5x12 narrow. Also,

  anyone have a good NMP pattern header they're willing to part with / sell? I've 

  tried Central Hobbies and APC with no luck. Thanks a bunch!

   

       Later!

              RJO
