Plans? Have we got plans. Here are a few off the top of my favorites list. If you can't find what you're looking for, post your needs here or over at Stuka Stunt Works and usually someone will have something they can sell or copy for you. Sig would probably sell you plans for their current production, too. Lots of fun to rummage in all these sources.
