RS Set with RSx3-12

  • This is useful set for HCS comaptible models.
    Receiver with RS Set setting is HCS mode in the channel 1. You can use HCS compatible servo without setting.

    * Some of the receivers in RS-set(#92391 & #92392) are wrongly set with Normal mode in the channel 1 for steering. Please check the mode by RX mode selector. If your receiver setting is Normal mode, please change it to HCS mode, using the RX mode selector. Please refer to a video guide for the change. We apologize to you for the trouble if it happens with your receiver.

    New HCS compatible

    The HCS mode shortens the communication time of the signal which has been compressed.
    KR-415FHD can change a mode to each channel 1-4 indiviually.

    HCS is a communication method to largely improve linearity of the servo movement. When using HCS mode, correspondence servos(ex, RSx3/BSx3series)are required. The correspondence servo recognizes both modes automatically.


    2.4GHz FHSS receiver includes dual receiver circuits​

    KR-415FHD achieves a highly precise receiving performance with the use of a dual circuit and an external and internal antenna. 

    The pale -type case desig

    This is 5.5 mm thiner  than previous models.
    So, Car gravity is  lower, and you can easy installation to the Radio box on the car.

    Shorter Antenna for Electric touring car.​

    Antenna normal length is 210mm.(Antenna socket to top of antenna.) And Short type is 90mm length.
    n the case of short antenna, Accesstable to install an antenna tube directly  to the receiver case.
    It fits into the body of the electric touring car clearly.

    How to change the mode.​

    1,Switch off the receiver and connect the mode selector to a channel that you would like changed.
    2,While pushing the set button on the receiver, turn the power source ON. When the LED of the mode selector lights up, the change is completed。

    The correspondence servo recognizes both modes automatically. So you do not change mode operation to the servo. 

    Initial setting of each channel

    Receiver with RS Set setting is HCS mode in the channel 1. You can use HCS compatible servo without setting.

    RSx3 12

    It uses a high-power core-less motor in luxury and secures high retentively and reliability.
    The servo adopts the aluminum gear to which hardening Alumite treatment is applied.

    The gear is strong in a shock and moreover shows an effect in the reproducibility of the driving.

    The black wire servo leads, attractive in a chassis layout, are used.

    Installed preset settings

    The following factory MODEL settings are pre-installed. 
    You can chenge setting by Servo model selector.

    Model1: Default setting(1/12 Stock class recommend)
    Model2: 2014 IFMAR setting (1/12 Modified class recommend,mild)
    Model3: 2015JMRCA Champion(1/12 Modified class recommend, Quick)
    Model4:  GT500, World GT, F-1 Rubber tyre class recommend
    Model5:  F1 form tyre, Asphalt road surface recommend

    *Model1 has been selected in factory setting.


    ICS Compatibe. 

    You can change servo's setting when you use our software" ICS Servo Manager".
    Ex, parameter of stretch. More retentivity in High grip condition, less retentivity in Low grip situation,
    You can select value by grip situation for best setting servos.

    Servo Model Selector

    The Servo Model Selector is a product that changes the model memory selection of KO PROPO RSx and BSx series servos easily.

    #What is memory of servos.

    RSx,RSx2,BSx2, RSx one10, Bsx2 one10.  Thease servos can memorize settings of each parameter  in a servo.

    You can change models of servos.

    #About the specification of the main unit

    Connect wire of Servo moel selector to Receiver.( or Battery) and connect servo to this Unit. You will know the model number memory by the number of flashes from the LED.
    The number of flashes of the LED are changed by pushing the button of the unit.

    Current model number is the pattern of flashes of the LED.

    Rx mode selector

    The HCS receiver can have each individual channel (1-4) mode changed.
    Connecting this product to each channel of the HCS receiver can change the configuration of the mode setting and can confirm the mode being used.
