Once you discover everything the 3PV is capable of, you'll realize that this radio can make a real difference on race day. Response rates are super-fast, programming is very intuitive, the LCD screen is large and easy to see, and the transmitter is lightweight and comfortable to hold. You get FHSS, S-FHSS and T-FHSS protocols, making the 3PV very adaptable. The included R304SB T-FHSS receiver provides telemetry functions for getting real-time updates on transmitter and receiver voltage while you drive - a real bonus for determining run time.
