JR also has a 6 ch. for 249.95. If you change radio systems your four ch. equipment can't be used on the new radio. Only the servo's will be used. If you want to add planes you will have to buy recievers. By staying with JR you will have equipment for two planes when you get the new radio. Tha last thing you want to do is have many different type of radios in your shop. In the long run having one good one is easier to handle, and cost less over the years. Most shops will do layaway. also look here for a used one. Dennis
