go with the 6 channel one. They are called 6x. There is another one called the 8u. It is overkill when starting out, but when you get into flaprons and want to name your models, and expand your model memory, it is a better radio. one simple thing is the display on the 6x is not much different from your microwave's display. the 8u actually has segments. i bought a 6x to start out with, and sold it 2 years later
