    steering servo twitching, won't center

    finished my rebuild and ran the truck for a couple of minutes, then the steering suddenly turned left and didn't want to self-center. Check linkages and it's all fine, spray some lube on everything and turn it back on. Servo is twitching like crazy and randomly goes to 2/3 left.

    Any thoughts?

    with the radio off the whole truck does the jitterbug and often runs away, so I never tried.

    Checked the Rx and it is clean and dry.

    You might want to call Traxxas. They can help you diagnose your problem.

    sounds like the servo pot is damaged.

    It was the transmitter after all.

    First I plugged in a spare servo from my 18T and it did the jitterbug as well, so I swapped radios and had no more problems.

    Disasembled and cleaned the pot for the steering today, but haven't got it back together yet to see if it works now. Hoping I just got a bit of dirt in the wrong place or something.

    I say bad servo. Easy to replace and if its still under warranty call traxxas. They'll take care of you, if not, it's not too expensive to replace.

    cleaned the steering "pot" on the transmitter and it's all good. Some metal dust must have gotten into it when I was grinding down my nut driver to fit into the Pro-line 17mm hex adapters.
