maybe it's a bad servo. or maybe your servo saver is to lose, check your manual for proper tightness. is anything binding in the steering system

A servo saver is a device for taking up the impacts the wheels are exposed for when it hit a rock or similar solid objects. It is normally mounted between the steering arms and the servo.

In front of the rods on the spring the steering arms are attached, and on the rear the rods from the servo are attached. The spring lets the servosaver twist itself and thereby saving the servo for the impacts.

Check the trim setting on your radio, if its set too far in one direction you will only be able to turn inthe oppositedirection its set at. Make sure your steering trim isset to the center positionon your radio and see if that was the problem.

hi tried that still the same thanks

Could be the end points need adjusting on your radio if it has them or the servo arms took a knock and the servo needs recentreing ie take off arm set tx and put servo saver back on dead centre.

If thats no good then its got to be a duff servo but why it would turn one way and not other? check servo gears inside for stripped teeth


ps thats this mean m8
post up what car and radio your using too to see if we can work out whats up with it

Disconnext the linkage from the servo horn to the steering....

Can the servo without load travel equal distance to each side ????
If yes then the problem is somewhere i the steering..... something must be binding.....
