Wellllllllll......... yes, you can use that radio for another plane, but it won't "remember" the first one with the trim settings and such. You CAN have one controller for all your planes, but the way I would do it is to buy a radio that has Model Memory in it, and at least 4 channels, because it sounds like you're going to stick with it. Buy a decent radio now so you won't have to buy another one later.
