Havoc4,
Buy at least a 6 channel transmitter. I really don't know why the industry makes 4 channel radios. This only makes the would be newby have to come back later for a radio with more functions. Few in this hobby limit themselves to 4 channels only. There is a fantastic world beyond Trainers, Cubs and the like. I love Cubs, but I have a greater love for Warbirds. Keep those Fighters and Bombers coming! Good luck.
