RSx4S One10X Servo Overview:

The KO Propo RSx4S One10X Low Profile High Speed Brushless Servo with 4 Selector has been designed for extreme 1/10 Electric On Road, 1/10 Electric Off Road and 1/10 Gas On Road. With "4S" Serial connection combined with technology found in KO Propo's "Flection" Servo making for an easy to operate servo. The use of "4S" serial connection allows for a super fast and reliable signal to the receiver. To top it off, KO Propo added REAL TIME ICS support to allow setting changes to be made through the transmitter that support ICS. Using the "Flection" technology allows for a inertia focus that aids in smooth turning performance with less stalling while firmly gripping the road surface. Powering the servo is a coreless motor that was designed to lighten the load required from the car's BEC. This reduction in power draw will aid in preventing receiver brown out and increase reliability. This combo features the selector that allows you to select the mode of the servo that best suites your driving style.
