New from KO Propo is the updated version of their EX-RR high-end transmitter that is soon available in three specific packages including the new KR-418FH receiver. Starting with the transmitter, while being left untouched in terms of the mechanical design the radio’s main unit comes with the new V2.1 software that offers a break-in function for gear and ball differentials. As many drivers opt to work and pre-heat their car’s differentials for a more consistent feeling on track, the function allows to set a time and throttle rate restricted action for precise diff working even at the starting line. The function can be assigned to the ET/BT key and a sound will indicate that the function is in use. Another new firmware feature is the hand brake function for drift car racers. It allows to set a hand brake function to the ET/BT key while still being on the throttle, which results in a more realistic and better controllable drift. In addition KO Propo have added software features such as a new All Reset function, the display now adds values for the 3CH/4CH positions as well as added changeable values for the gyro mode of the third and fourth channel. The V2.1 firmware is rounded out by a updated steering direct function and minor bug fixes. The radio system is available with the new KR-418FH receiver, as KR-418FH double receiver set or as Drift specific set including the KR-418FH, a KG-X gyro and RSx3-one10 Ver.D servo.
As for the KR-418FH receiver, the unit supports KO Propo’s own HCS Highspeed Communication System for greatly reduced responding times compared to the Normal mode and it features a shield black-colour antenna for improved noise filtering, it is compatible with all transmitting modes and is fail save function ready. The 4-channel receiver is high-voltage compatible, it measures 28×18.3×18.5mm and weights in at 7.5g.
