KO Propo have dropped their all new EX-Next transmitter and KR-420XT receiver. Equipped with a new standard called ‘XT’ that they claim achieves the fastest communication speed in the industry. An all new control and radio communication software was developed making it about 3 times the speed of the EX-RR. High-speed communication in the XT advanced mode improves the information density that will be sent to the receiver for a smooth and more responsive feeling. The EX-Next also 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 you can use realtime ICS allowing you to easily change parameters of the servos from the transmitter without accessing the car directly. Even using the XT Telemetry mode that is 2-way communication, the high-speed response, while slower than XT advanced mode is still faster than the EX-RR.
Currently, mainstream servo control method is performed by PWM. The PWM control method uses pulse width to send position of servos output from receiver. Serial control method uses a digital signal value to send the position of the servo output. So, communication speed of the Serial control method will be significantly faster than a PWM control method, making the time of the servo’s action from your operation input shorter.
