        Zero deadband provides the legendary precision of JR

    Overview:

    For nearly as long as the JR name has been synonymous with unsurpassed control and feel, it has also been synonymous with compact, powerful servo designs. The latest generation of JR® servos is no exception. Offering the performance you expect, while also being optimized for use with the newest battery technology, this premium servo from JR is the mid-size digital DS9411HV that has ultra torque, metal gears and equipped to work directly with 2-cell lithium power packs.

    Imagine locating servos where no servo has gone before. Due to their compact size, these small digital ultra-torque servos are perfect in applications that require servos driven by space restrictions, such as those found in a jet, sailplane, pylon racers, or a complex scale model. Eliminate long accuracy-robbing linkages by locating servos closer to the point of operation.

    The DS9411HV servos are truly in a class of their own.

  7. 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.
