How To Look Up Servo Frequency And Center Position Wavelengths

  1. coolgabsi
    We get asked this question a lot . What is the center frequency of such and so servo.

    Not just helis but plane guys and quad guys need that info cause its a part of programming your gyro

    So here is a very simple and extremely reliable way


    Even if you aren't using beastx ... That's ok... Servo specs don't change gyro to gyro.

    Just go to this website and select version (highest) .. Right now it's 3.0

    Then select language

    And it'll populate a list

    On cyclic the servos have a different frequency than on tail sometime

    So use that

    The center frequency wavelength is good to know!

    As all spektrum rx's only out out 1520us and if you hook up a servo like a 9256 (which is 760us ) straight to a rx you'll think the servo is bad cause its not moving. Futaba rx's and most allgyros can put out 760us cause you can program them for it .. That's a need to know info before you plug in a Servo to something

    So use that chart for any servo you got


    Fly safe!! :) have fun!
