Ultra high-speed response "XT" compatible
The EX-NEXT is equipped with "XT" that is progressed more from "FHSS" in combination with the KR-420XT. You can choose RF mode from XT advanced mode which is fastest response in the world by one way communications and 'XT telemetry mode' which is supported telemetry(two ways communications).
You can feel most fastest response by EX-NEXT and KR-420XT.
*The telemetry function can only use with our serial compatible products and receiver's power voltage.Port on the KR-420XT
The figure below shows the port of KR-420XT. There are total 5 port. Most right side port is B/S port. In case of using serial mode compatible servo, connect to this port. 1-4ch are same function as conventional KR-418FH and KR-415FHD.You can use conventional servos.
Equipped with a terminal compatible with serial communication.
KR-420XT is supported 'REAL TIME ICS" that is new serial communication to servos. It became to change setting data of servos by wire-less from transmitter in your hand. You can use "REAL TIME ICS" with connect to B/S port from BSx4-one10 Grasper2 that is supported serial communication.
There is only one B / S port, but you can connect two or more devices by change the device ID number and using a branch cable. So, You can use "REAL TIME ICS" in the GP car or else category too.
Example for wiring serial servo.
When using two serial servos
If you use 2 servos with GP car, connect 2 servos to B/S port with using Serial Branch adapter or Servo Twin Extension Wire II w/new plug. it is necessary change ID number to 2 using for throlle servo, but it is easy to change by connect to Xpansion of EX-NEXT.
Ultra small dimensions case
At the ultra-compact receiver KR-420XT, which is equipped with the latest devices abundantly as like EX-NEXT, While maintaining the same occupied area as the KR-418FH compact receiver, which has been very well received, the connector mounting height has been reduced, and the total volume is smaller than before. Connecting port for servo or ESC are equipped total 5 port.Also, not connected port can be use to power supply for cooling fan and transmit ponder for lap count system.
Supported HCS.
EX-NEXT & KR_420XT are supported HCS that is adopted from RSx3 BSx3 series.。Until now, it was necessary to change the receiver mode using the setting device, but with EX-NEXT, it can be changed from the transmitter each channel.HCS compatible servo are automatically change to HCS mode when received signal was HCS. If you want use HCS, please connect to 1-4ch of KR-420XT.
<Compatible Servo> RSx3 / BSx3 Series/ BSx4S-one10 Grasper2
NORMAL mode (for General Servos, ESC.)
You can using more kind of servos by changing to "Normal mode" by the response mode. So, you can use your have servos and ESC with EX-NEXT. In this case, please connect to 1-4ch of the receiver.
*If you change response mode of EX-NEXT to NORMAL at XT advanced mode of Radio setting, maximum movement degrees of servos are limit to maximum about xx degrees. So, if you use NORMAL mode, we recommended set to XT telemetry mode in the radio setting. In case of using ESC, there no chance for using over this limit, so it is no problem for using with XT advanced mode.

Can pairing device with turn on power.
The UI (user interface) of the setup switch and pilot LED has also been reviewed, and in addition to the same handling as the conventional KO PROPO receiver, pairing and RF mode switching functions have been additionally implemented without turning the power on / off.
