Ok so if we did that we'd have to put out a "Not Allowed aircraft list", silly idea. I'm all for allowing any AMA legal airframe to be flown in sportsman. Heck i saw a guy fly a heli in a pattern contest once. I've found some of the "Serious" pattern guys that want to compete on the national level never fly in local contests and pratice at private fields and I'm fine with that. I've flown with many "National" championship winners in these parts and they put their pants on one leg at a time just like me and you. They'll also help you at any time you need it. I recieved more than my share of help from probably the finest man ever to fly pattern, Darrell Kampschror. He designed, built and lent out more airplanes than anyone I know of. He let me borrow many airplanes over the years and when I crashed my airplane just before the first NPAC, one phone call and I had an airplane to use in under 2 hours. I flew that airplane to first loser that year in advance. I choked and let David Shulman beat me. By far the avg pattern flier is more than happy to help anyone that needs it. When one wants a national championship or to try out for the USA team they need private practice time with the coach. It's part of the game.
