The resolution of a radio system can be one of the most over-hyped and misunderstood terms out there. Resolution refers to the number of steps your radio has in its range of motion. A higher resolution means that your radio has more steps in its range of motion. One would naturally think that the higher number would be better, but there comes a point where the numbers lose relevance. Yes, a higher resolution number is better, but there comes a point where the resolution of a radio surpasses the resolution of the servos or ESC, making incredibly high resolution claims irrelevant. In other words, resolution is only one element in a series of events that have to happen; the system will only ever be as fast as its weakest link.
