    $39.99
    NX588 XBus Pro Sport High Torque WV Smart Servo

    Overview
    JR - JRPSNX588 - NX588 XBus Pro Sport High Torque WV Smart Servo

    NX588 XBus Pro Sport High Torque Smart Servo™

    Looking for a standard-sized digital servo for your sport airplane that won’t break the bank, but don’t want to compromise performance? The NX588 is surprisingly strong and precise, and surprisingly affordable. With advanced programming not found on any sport digital servo on the market, the NX588 is the ideal choice for your next building project.

    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 NX588 servos from JR and feel the difference the new JR NX Smart Servos™ can provide.

  5. DS8411HV High-Voltage, High-Torque Airplane Servo
    $124.99
    DS8411HV High-Voltage, High-Torque Airplane Servo

    DS8411HV High-Voltage, High-Torque Airplane Servo

    Features:

        JR® Slow Start technology
        Standard size case that fits nearly anywhere
        Zero deadband for extreme accuracy
        Rock-solid holding power
        Dual ball-bearing support
        For airplane use only


    Overview:

    With 239 oz-in of unbridled brute strength, the DS8411HV is the most powerful JR® standard-size servo. Composite and metal materials assure that the gear train will hold up to tremendous loads, while offering substantially improved wear over conventional brass units. And now, it’s able to support the latest Li-Po battery technology without the need of a regulator. This version also offers a boost in output, and features exclusive JR slow start technology that respects your decision to have the ultimate in precision. For giant scale and precision competition airplanes, the DS8411HV servo features not only high output torque but also incredible accuracy and holding torque. To transfer all that available power to the servo arm, the jewel movement of its composite and metal gear train includes a combination of hard-anodized steel and brass gears that are virtually unstrippable. In addition, ball bearing spacing on the output gear is ideally spaced to prevent radial output play and assure accuracy when loads are at their peak. The JR servo digital amplifier, developed in cooperation with the electronics giant Mitsubishi, features a high-frequency 250Hz pulse rate (the number of times per second the amplifier sends power to the motor) versus the 50Hz pulse rate of conventional servos. This provides quicker response and gives up to 5 times greater holding power.
