    Slash Steering Problems

    Hi. I have a slash 4x4 that I have had for 2 weeks. It of course has the TQi Top Qualifier radio system and I am having problems with it. First off, I have to set the steering trim all the way left for it to be straight, or it drives right. Second, it makes a screeching sound when I turn right. These problems seem like they would be an easy fix but I am new to RC so I don't know a lot. Please help!

    Put back your trim at 0 then re centre and re align the servo physically.

    Unscrew the servo from the link and horn. Swicth on the transmitter then the esc and making sure the settings are 0 trim. This will re-centred the servo to its end points, then you can re link the horn and arm on making sure the tyres are straight when you connect everything.

    If it still happens then chexk your bellcrank if that is fine it could be that the servo is damaged

    When you say "screeching sounds" do you mean a clicking noise? because i have had hat happen to mine, and all i did was replace the gearing in the servo and it worked great after that! But if i'm wrong, as i always would do, look it up on youtube, i'm sure you are not the only one to have this issue.

    I think what he means is a buzzing sound that occurs when the servo is binding.

    First of all you have to recenter the servo by hand.

    1) Remove the servo horn
    2) set steering trim to neutral
    3) put back the horn with tires as straight as possible
    4) now only marginal trim is requred

    If now anything is binding you have to shorten or lengthen the link. I found that from the factory the links are often not perfectly set. It takes some try and error to set it right. Just take you time and dig into it

    That sounds like a broken servo to me.

    Before you go get a new servo, closely examine all your linkages and steering bell crank.
    Maybe a twig or piece gravel is wedged in there somewhere.
    If it is, just work it out and you should be good to go!
    Hope that was it. Cheap and easy is the best kind of fix!

    True. Could also be stripped servo gears or just something got stuck in the steering mechanism.
    Both already happened to me.

    Is it a screeching or a buzzing sound. My servo makes a buzzing sound every so often. I think it just means there is a load on it.

    The arm that is attached directly to the servo.

    The gears are not stripped, but there is a lot of grease in there. Should I scrape some of it out of there?

    No leave it as is. With the servo detached check the steering for binding.

    Next you could reset the radio.

    Place the truck upside down and move the linkage the servo attaches to. The tires should steer left and right without any resistance.

    Ok than no mechanical issue. Must be the servo, receiver or radio.

    So what is the servo doing if you steer left and right without attaching it to the steering assembly?

    I am off for today. Maybe someone else can help from now. Good luck. We will find the problem for sure

    The white part on the bottom that the horn connects to moves left and right.

    Sounds like the servo saver is moving on itself. Plastic against plastic squeak. Does it do it if you hold the front end up in the air?

    part #6845 in this diagram.

    No it does not when in the air, but it still makes the electronic sound as you can hear in the video. I don't know if its coming from the servo or receiver.

    Every Traxxas vehicle I have ever had with the Tra2075 servo makes that same buzzing sound. That is a normal operating noise. It seems to make the noise when there is a slight load on the servo.
