centering servo?
 

Ok so I am going to program my car and everything tomorrow. When I center the servo how should I do it? turn the car on and let it center by itself then put the arm on?

Please explain if thats wrong, thanks

Pretty much... make sure that the servo trim is centered on the radio as well as any sub-trim setting... turn it on.. let it center and put the arm on.. if it still isn't centered on the car, you probably need to make some linkage adjustments to get it closer.. then sub-trim it out.

cool thanks a lot.

First center servo horn like mentioned.
Then sub trim to better center if you have it.
Then adjust endpoints.
Then use normal trim for further fine tweaking.

Note sub trim changes endpoints, normal trim does not.
