I'm new to the whole concept of e-flight. I've had nitosr up n running for years. When I want more power I put on a bigger motor, .40 to .46; but how are brushless motors rated. I'm spec'ing out for a t-Rex 450 and most motors are 3200kv - 3400kv, what does this mean. Which one will have more power, and is there a way to figure out how big of a ESC I'd need?
