Another resource is www.airfieldmodels.com Looks like they have allot of good info on systems in general. I have one of the Great Planes magnetic building board systems that I bought years ago and it looks very similar to what they show.I like it for various projects that require stick building and alignment. The steel sheet has a grid printed on it that comes in handy for alignment of various components....I don't use for every project but on my current build, a VK Camel, it will come in handy.
