    Noisy/jumpy servo

    Hi guys just noticed that my servo is rather noisy, it seems jerky and it you turn it tight to one side it makes a funny noise and jerks a little, any ideas?

    Ok guys, so my stock servo has died again!
    I've decided to upgrade and have just received my ******* 390
    It's all installed and works great but it has a constant buzz when under stress and sometimes when in its normal position.
    Is this normal? My 2 stock servos did the same, I just rather not fry this one too!

    I was hoping someone would say that lol! I did read somewhere that it's because it's a digital servo ?

    Nah the stock is digital also...the system is setup for digital and if you don't use one it will twitch and make a bunch of noise, but it's not uncommon for aftermarket upgrade servo to make a little noise. The gears are strong and the motor is barely doing anything, so it's not a big deal unless there is some serious binding in the linkages or something.
