Spektrum S603 servo is glitchy

[jessperk56]

New to this. Have an ECX I just got. Have adjusted trim all that. When just sitting or driving, servo pulls to one side. If I shake the controller wheels bounce from left to right? Not if I hold the wheel, though. Don't trust myself to tear apart the transmitter. Help me please!? Also, can I install a bigger brushless motor on this?

The transmitter should have steering end points as well as a tracking.

Pull the servo horn off. Put the wheels straight. Turn the transmitter on and set the servo to straight ahead no trim/tracking. Put the servo horn back on. Adjust that or the length of that steering link between the servo horn and the steering assembly.

Inspect steering and suspension components for wear or damage. Focus on the side that it’s pulling to. Check wheel bearings etc for excessive drag. And get the skid plate back over that steering linkage pronto

In my personal experience I have not had any luck using anything Spektrum. I've had good luck with many off brands and they don't break the bank.
