This is compatible for HCS function set of receiver Servo and Servo model selector.
This is a more advantageous set than purchasing for each product.

Receiver setthing of HCS is  HCS mode in Channell1 by factory. You can use servo of the product without receiver's setthing.

■Compatible for H.C.S

HCS (High speed Communcation System) is the new high speed communication system between the receiver to the servo. The HCS mode shortens communication time of the signal which is compressed. HCS compatible servos is changing mode automatically by signal from receiver. So HCS compatible servos can use with all receivers.

If you want to use servos by HCS, please use with HCS compatible receivers. 
Please visit our explain for HCS.

RSx3-12 H.C

More precision and the installation rigidity are improved by the adoption of the aluminum top case, with only a very small difference in weight from normal RSx3-12. More linear steering can be felt.

Installed preset settings

The following factory MODEL settings are pre-installed. 
You can change 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.

KR-415FHD

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 design

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.
In 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.

 

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.

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

In this product,  Channel 1receiver setting  is HCS mode. So you can use Servo in this product without receiver setting.
Channel 2 setting is Normal mode. So, you can use your ESC without change.

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, Bsx series(except Bsx Standard).  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.

#Product usage

Factory setting of each servos  are diffrent. Now(May 2016), No.1 to No.5 memories are same parameter.
But BSx2 one10 Grasper has 2 diffrent model in memories.

Model1 is High spec setting for expert racing. Model2 is more mild setting for drivers. Factory default setthing is model2.
If you use Servo model selector, you can change models of servos easily. 

And you can download some servo setting from our site. Ex RSx12 are 5 setthings in our site.
