I'm having issues turning left(won't go to full lock) and when I turn either way it won't retract to the center.. I replaced the servo and am still having the same issue, I made sure the bearings and everything for steering aren't binding up because the servo is constantly humming and sounds like it's fighting to turn. Also tried changing the power switch thinking it was something electrical but that's not the issue as it continued so I put a nickel battery pack in and again nothing changed so I'm at a stand still with my trouble shooting I have no idea what is causing my problems as I tried putting another brand new servo in and it still hummed like it was fighting itself.
I'd appreciate any help.
Thanks in advance
