You can choose and use from "XT advanced mode" which is the world record response for one way communication and "XT telemetry mode" which is compatible for Telemetry ( 2 ways communication).

XT Advanced Mode

An all new control software and radio communication software of the EX-NEXT has been developed. World record communication response and High resolution control are installed.
"XT Advanced mode" that is the highest speed in EX-NEXT is about 3 times the speed of the EX-RR.
The performance far exceeds the conventional high-speed communication.

High-speed communication in the XT advanced mode improves the information density that will be sent to the receivers.
You will feel a "Fine and smooth maneuvering feeling" by unprecedented high-definition and high-resolution control when operating.

XT Telemetry mode

EX-NEXT supports "XT Telemetry mode" that uses 2-way communication. When "4S series servos" that support serial compatible are connected to the B/S port in the new receiver KR-420XT, you can use "REAL TIME ICS". So, you can easily change parameters of servos from the transmitter without accessing the car directly. Setting your car with more freedom and more detail without compromise.

Also, even using the XT Telemetry mode that is 2-way communication, the High-speed response is still faster thanthe EX-RR.
