Technical Experts Needed!

We would love to have 5 or 6 "experts" that would agree to monitor this category and provide the best answers they can. Now, not everybody knows everything about everything, so we won't expect 5 or 6 answers to every question from all our "experts". And, of course, anyone who has an opinion is free to express his opinion, too.
BTW, by "experts" I don't mean AP/IA, or anything like that, just someone who has skinned their knuckles on an Ercoupe. Anyone game to help out fellow coupes?
