There's also the library that Al put out that has lots of great info, with "Book 2" particularly having around 300 pages dedicated to the Mustunt IV.

Been trying to read this hear and there.  Really neat stuff.  The more I read the more I think I may have these on CD.  Got to remember where however.

I did get the plans for the 4 downloaded and printed out.  3 I actually found by accident on Ebay of all places.  It was actually cheaper there to get the plans then to download it and print it out here locally.  Plus it comes with the article. 

Still searching for a canopy but also thought of a Spitfire canopy would probably also work.  Something to check into.  I could try and make my own.  Never have but I guess there is a first time for every thing.

All of the above has been collected from the interwebs over the past several years. I own none of it; all credit to original publisher(s) and of course, to Al!

Steve

You’re in town?  You should stop by. You should stop by Steve’s, too, but his house is hard to find, even with a GPS.

OK. So your uniflow line is fixed inside of a metal tank? I am looking for a 4-4-4 or 4-2-4 stunt run with mostly 46la’s and Brodak 40’s and am just learning. With my set up I do get 10-12 lean laps at the end after the pattern is complete. My fixed uniflow line is bent to angle to the outboard wall of the tank and i have had some luck twisting it to move the end up or down to get even runs right side up and upside down. The method you described, sounds better and simpler, but I would have to start making tanks
