JR - JRPSNX6421 - NX6421 Pro Mega Torque MG WV Smart Servo

NX6421 Pro Mega Torque MG WV Smart Servo

The NX6421 servo from JR is a clean sheet of paper approach to designing the ultimate giant scale servo. Boasting over 500 oz/in torque, the NX6421 is housed in a sleek all-metal case with thicker diameter case pins and a stylish, yet effective, heat sink center case. The helical-cut gears are nearly twice as thick as other servos for more contact area and better mesh for smoother operation and greatly reduced geartrain wear. Additionally, the NX6421 is fully programmable and each servo can be customized and fine-tuned independently of one another.

Featuring automatic output detection, these new JR Smart Servos 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.

If you're looking to take the performance of your model to unprecedented heights, take a look at the new NX6421 servos from JR and feel the difference the new JR NX Smart Servos can provide.
