I'm about ready to buy a new radio, one that I can use for a long time to control just about any plane I come across. I've narrowed down my search to include JR 8103 and Futaba 9C. How do these radios compare? Is one, or both, missing something I just can't do without? I don't plan on flying competitions but I want to be able to control a warbird with retracts, flaps, etc. and/or a aerobatic plane. I would really appreciate everyones opinions and suggestions. Thanks.
