I have a 7955 Hitec. When I turn the wheels to the left and right the wheels don't line up the same way each time. If I turn to the left and let go of the wheel the wheels don't come back to the ezact same spot as when I turn the wheel to the right and let go. There close but not perfect. There is no twitching or any obvious signs of being bad.
Do you think my servo is going bad or is bad?
Thanks

ive seen this happen with mine check for a stripped servo arm and let us know.

Check the servo saver too, maybe it has gotten lazy And also check that nothing in the linkage of the steering system is binding.

Could possibly be the karbonite gear. I had one strip after 2 years of use. They are $10 for 3 of them. Can't complain about that

I'd check servo horn, servo saver and binding within the steering linkage first. Then go onto troubleshooting the servo gears. I had a servo partially strip and did this, ended up being internal to the servo.
