I am in the market for a tx and rx for racing purposes and I have a few questions on what i should be looking for.
1. What defines a good tx and rx?
2. What is the difference between 1 channel through 4 channel?
3. Is paying top dollar for a transmitter going to pay off?
4. Does anyone have any recommendations?

I will be running electric. Esc, fan , servo, transponder.
