This is KO PROPO EX-2 ST2 2.4GHz Transmitter Radio System w/ KR-241FH Receiver. We adopt new angle sensor which was particular about the durability and the feeling of operation for both steering and throttle. Prevents deterioration of durability and operational feeling due to wear, which can be said to be the problem of contact sensors. Along with smooth operation feeling by smoother sliding, we realize high durability that is approximately 100 times compared with the prior sensor. Therefore, the best feeling of operation can be maintained for a long time. In addition, the new sensor outputs a more linear signal to the Master Unit. You can control the ESC and servo with a detailed operation sense. A realization of a sense of unity between people and cars.

Increased the number of ball bearings that support the steering shaft for higher accuracy! The number of ball bearings supporting the steering shaft has been increased from one to two. The double-support type supports higher precision operation and reliability. The normal spring included in the extension unit has been modified. The previous spring used was a progressive spring becoming stiffer as the wheel angle increased, but the new softer spring give a linear stiffness as the wheel angle increases. Since the spring tension can be adjusted, you can set the spring tension to your personal preference.

This new function has been added to the calculator in the EX-2. Put TYRE DIAMETER in the calculator, ROLLOUT( Car movement distant per one motor rotation ) is automatically calculated. This is useful for changing gearing in a DD car. 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. This is effective for F1, WorldGT and 1/12 category of cars whose gear ratio is small.
