What brand and model is it? Almost any modern radio has a trainer port that can be interfaced with a pc, but until I know what kind of radio you have it would be difficult to recommend how to do it. Also, if you are going to be flying for long, you will want to upgrade to AT LEAST a 4 channel controller. I personally have a Futaba 8U 8 channel radio and it is a dream. You can find them really cheap on Ebay, because everyone is upgrading to 9Cs or 14MZs.
