    I had the same probem with my revo and emaxx.

    Adjusted the steering link so the servos were not fighting each other. On the revo I had to take the arm off the servo and adjust the 2 turnbuckes to get good alignment.

    Now both trucks are quiet on startup and the steering seems more even.

    Unhook one arm & you will see how far off & which way you need to adjust the turnbuckles.
    Split the difference between the two tunrbuckles & humming will stop. Takes some time to get it adjusted up..

    Ok thanks guys! I got them to stop humming but I also discovered that one of my e revos wants to start slowly reversing without me pushing the trigger any way. Iv tried to ajust the throttle trim and it doesnt do anything or do I have to press a button to get the throttle trim to work. The other thing I think it could be is the throttle endpoints iv tried to set that too but it doesnt seem to work.
    That's me!

    The Back of the manual has directions for how to adjust radio parameters, including throttle trim. I'm not a fan of doing this on Traxxas radios. I'm spoiled by radios with on-screen programming. Recalibrating the ESC and transmitter would likely fix your issue. It's on page 16 of my E Revo manual.
