Most of the information is contained within the "Nn3 Manual" by Robert Sloan. I cannot reproduce the information unless I get permission from the publishers (NTRAK Publishing, 1150 Wine Country Place, Templeton, CA 93465.). I will clear it with them before reproducing any of the info. The easiest way is to get the book. Ask at your local hobby shop. They should be able to find it for you. Alternatively, search some of the hobby shops on the web. It has a lot of the basic information you need to get going and to keep your efforts within bounds.
I will be adding more information as it comes up.
