The truggy comes with a bigger motor otherwise they all have the same parts outside of the wheels/tires, bumpers and bodies.
For the servo here is a replacement one. The size makes it difficult to find aftermarket options. There is a floating servo mount which allows you to use different sized servos but I can't remember who carries it.

That's the servo I have installed right now. I'm thinking maybe the plastic servo horn is stripped. When I took off the servo horn and readjusted/centered the servo it turned both directions fine. When I began running the car is when it began turning fine to one side and not so much the either. I ordered a metal servo horn to see if that fixes the issue.
And it looks like that servo mount is only for the 1/12 vehicles unfortunately.
