KO Propo have introduced the new EX-LDT radio. The “LDT” (Lay Down Trigger) means that the trigger operation axis has been rotated 90 degrees so that you can squeeze or press naturally with your finger tip. As everyone’s finger size is different, the fingertip is adjustable by moving spacer by 1mm step increments and maximum 5mm. The throttle unit is adjustable by hand size or finger length and the tension of trigger spring can be adjusted to your preference. The standard trigger width is 17mm and a 21mm width lever is included to suit as many possibilities as possible. The nw angle sensor used in the throttle is the same that is used in the Expert Grip2 and Drop down extension2 which was particular about the durability and the feeling of operation. The EX-LDT radio features the new Push Control 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. The LCD screen can be placed in two directions for a preferred viewing position while the new mounting bracket for the LCD provides a stable mount. Another new function is the Rollout Calculator; also seen in the EX-2, this allows for the calculation of the rollout (car movement distance per one motor revolution) automatically. The radio can by charge by connecting to the stand, without removing the battery from the transmitter.
