High performance CPU &

2.7inch LCD

Using a similar CPU to the EX-2 provides a super linear and fast response with new added functions. Each menu is displayed like an icon to make it easy to search and the new menu tree is useful for setting up to 40 vehicles.

Two LCD Positions

90 Degrees Conversion

The LCD screen can be placed in two directions for a preferred viewing position. The new mounting bracket for the LCD provides a stable mount.

Compact and Light Weight

Master Unit

Using a similar Master Unit as the EX-2 provides a compact, light and well balanced system. The Master Unit and grip panels have a carbon fiber water dip wrap and some screws have been changed out for aluminum for further weight reduction.

Newly designed throttle unit has

increased the direct feeling.

Changing the fulcrum point, lengthen the trigger, adding a spring tension adjustment along with a new angle sensor has created a more direct feeling while maintaining a compact and comfortable size.

Smoother Steering Unit

Optimized Wheel Size

A new soft linear spring gives a constant tension through the steering movement. The new wheel size has improved the reaction of a car operation.

New Function

Rollout Calculator

Also seen in the EX-2, this allows for the calculation of the rollout (car movement distance per one motor revolution) automatically.

New Function

Push Control

A motor that has a strong magnetic force will add a braking effect when the throttle is released and will make a car stall in the corner. Setting the amount of forward input to remain on the throttle as the trigger returns to neutral can be adjusted.

Includes the new receiver

KR-415FHD

The new dual receiver KR-FHD is included and ready to be used with the Normal mode or HCS mode when turned on. The long antenna version is included with the set.
