Can drive motor affect steering servo?

[sparkycuda]

Tried the easier "fix" first and added a Radio Shack snap-on ferrite core choke on the steering servo lead. The servo uses a large, twisted wire bundle and could only install one bundle through it - not wrapped as discussed. Guess what? The truck steers perfectly now! Even moved the servo back to its original position - still good! Then I tried using the ESC-BEC instead of separate battery - not good - the servo dithers on its own, but not in relation to motor speed. So tomorrow I install the external BEC and we'll see if is okay.

Thanks to everyone for suggestions. Now to finish the cab mount and see about a video.
