If you want to fly a glow engined airplane, go to Value Hobby and you can choose from several sizes and types, including a Stik if you want that. But even the 25 size Aviator can be flown in a lot of wind... Balsa/Fiberglass Planes - Airplanes | Value Hobby

For a field box with basic equipment go to a swap meet or ask in your club. Used glow stuff is really cheap these days because of estate sales and people switching to electric. Engines in good shape go anywhere from free to $40 or so. Pick up a couple of them, get a couple of new glow plugs and fresh fuel, try them out on a test stand. If you're in a club, there will be someone, or a few people, who are handy with glow engines. Learn from them, it's not hard once you know the basics.
