Futaba 4pl Steering Problem
 

I have the Futaba 4pl controller. When I turn the wheel fully in one direction and slowly release it the servo jumps sharply in the opposite direction. Tried rebindingredients it but that didn't help. Put in a new servo & that didn't help. Tried a glitch buster but that didn't help. Servo is a Savox 4096 Coreless. Glitch buster was Spektrum.

Didn't make any changes to the controller before today. It was working perfectly. Started to happen at practice.

Any suggestions? Thanks in advance!

Did you make any other changes? ESC, motor, receiver, etc?

I noticed with the 4pks that sometime the radio has to be changed from reverse in the settings. Could it be that simple ??

I suspect the issue is letting go of the wheel. Every controller/radio wheel I've ever seen when released will overshoot the other direction and bounce back and forth a bit until it settles at center. The servo is only following what the controller is telling it to do. The solution is simply holding on to the wheel, maintain control. Seen this concern several times over the years.

About the only way the controller could be designed to avoid this is by adding damping to the wheel. Which would make quick steering corrections harder. Either that or eliminate the centering spring.
