KO ProPo have introduced the new EX-2 ST2 2.4GHz radio. Based on the high-end EX-RR radio, the EX-2 ST2 features a new sensor for both steering and throttle offering excellent durability and operation feeling. It prevents decrease of durability and operation feeling due to wear, a common feature on this type of sensor. The new sensor achieves a smooth operation feeling while the durability much more higher than conventional products. In addition, the new sensor outputs a more linear signal with respect to the operation amount. The steering shaft uses now two ball bearings instead of one and associated with a double-sided support, the steering provides a more precise operation feeling and reliability. The spring of the extension unit has been changed to a soft type. The tension of the conventional spring becomes stronger as it is tilted, but with this soft spring, it can be operated with almost constant force even if tilted. In addition, the tension can be adjusted, so you can adjust the spring tightly and change the strength of the “overcoming feeling” when passing through neutral. The EX-2 ST2 2.4GHz radio works with the latest V2.12 software and comes with the KR-241FH receiver. Its availability is expected in August.
