KO Propo EX-NEXT Black SP

The KO Propo EX-NEXT Black SP 2.4GHz Radio System is packed with so many features you aren't going to know what to do with them all. The most impressive of these features has to be the XT Advanced Mode, which gave KO Propo the world record title in communication response. Along with a world record in speed, the EX-NEXT Black SP comes painted in a luxurious black pearl and coated in a matt texture for a soft sumptuous feel.

XT Advanced Mode: About 3 times the speed of the EX-RR. The performance far exceeds 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 smooth maneuvering feeling by unprecedented high-definition and high-resolution control when operating.

XT Telemetry Mode: When 4S servos that support serial connection are connected to the B/S port in the new receiver KR-420XT, you can use the REAL TIME ICS. This will allow you to easily change parameters of servos from the transmitter without accessing the car directly. Setting your car with more freedom and more detail without compromise. High speed communications in Telemetry mode Even in XT Telemetry mode that is 2-way communication, the High-speed response is still faster than the EX-RR.
