What radio to start out with?
I would suggest not going too cheap on the radio. It can last a long time if you get a good one. Make sure it is able to buddy box with the guys at the field and get at least 6 channels. That way, you don't need a new one as soon as you get a new plane. You can use it for a few years and grow into it. There is no reason to get the cheapest one and have to get another one in a year. Spend a few bucks extra now, and next year you can get two planes instead of a plane and a radio.
