servo help
 

I have had various servos fitted in my MI3.5 Schumacher touring car and all seem to give the same problem.
When I return the steering joystick to the center position, the servo seems to judder before centering and in some instances, does not return to dead center. This is noticed with the car on a pit stand (so no load). I do have a servo saver fitted to protect the servo but it did the same thing without the servo saver.

The servos in question are bluebird, Inolab and Scanner, not high end servos I agree, but surely these can't all have the same symptoms.

Could it be that the deadband from the transmitter is too small, so in essence as the steering stick returns to center, it may actually slightly overshoot and give an opposite steering direction signal? Could it be the spring tension in the transmitter is too stiff?

I run a Core FHSS 3 channel set.

If I buy a high end servo (KO, Savox etc...) will this symptom stop?

Any advice is welcome

The CORE is the problem, apparently the newer blue receivers are better but I believe the problem still occurs
