Brand or price is not your first choice. Remember if you buy on price only and later want more radio the best you can do is get back half. In fairness you must add that to the price of the new radio. The number of planes in the memory is unimportant. it's the computer power and channels that increase the price. For example. My GS planes are really only 4 channel planes, but I use all 9 channels and up to four mixes. My jet uses 9 channels and several match boxs as well. Will you ever own these type of planes? Maybe not now. I said at one time I wouldn't either,, but here I am. My advice is to buy the most you can afford now and not have to do it later. You will grow into the radio and use more of it's capabilties as time goes by. All the radio's play good together. Pick one and have fun learning what it can do. On my new plane I'll have 15 servo's and a smoke system. Wish I had a radio for each servo. Dennis
