There's another category of modeler - the dumpster diver. Too cheap to buy any new balsa or kits. Pulls all of his material out of a garbage can after someone else's crash. Planes are covered with scraps of monokote no bigger than two inches. Every engine they own is worn out and takes 15 minutes to get running. They only use Fox plugs and flexible nylon props that haven't been produced in 20 years. Every time they go to the field, it's like the Wright brothers first attempt at flight - it's a miracle if they actually fly.
