The DS3421 and DS3711HV have been staples of many serious modelers' equipment inventory for many years now because of their compact size, unparalleled precision, and remarkable torque. They are perfect for competition aerobatic models, jets, and even giving a performance upgrade to your favorite sport models.
Featuring automatic output detection, these new JR Smart ServosTM can be used with either conventional (PWM) or XBus installations for ease and flexibility. Programming is simple via your XBus-equipped JR XG-series DMSS transmitter, and not only can servo direction and travel be adjusted, but it is now possible to fine tune holding power, stopping speed, deadband, starting power, total servo travel, create an alarm if servo load exceeds a user-set limit, enable slow start, as well as enhanced failsafe features to help protect your servos in the event of signal loss.
