Do you have a Futaba radio? These Tower Hobbies receivers work great and are only $50. http://www3.towerhobbies.com/cgi-bin...I=LXMFU6**&P=0

You may be tempted to use your old receiver. There's a chance that it might even work fine. You can get lulled into a false sense of confidence that way though. I've seen that happen all too many times. People get away with things and they start to feel that what others describe as risky is really no big deal. After all, they did it before. In RC that will eventually lead to a crash. In full scale flying, industry and other situations it often leads to someone getting killed.
