Just found out that you can adjust the steering using the alignment screw on the bottom of the chassis without turning the car off and on. Here's how:
Turn the car over and press the throttle.
With your finger on the throttle so that the motor is revving, turn the alignment screw with the adjustment screwdriver. The fronts will adjust while you screw (so to speak!) so you don't have to micro adjust by turning the car off and on.
There seems to be (as others have noted) right turn sensitivity. Has anyone tried removing the flat gear and then centering the car and controller steering trims so that the servo turns an equal amount in either direction, THEN re-assemble with the flat gear and wheels centered? Just a thought that I might try. Wanted to see if anyone else has thought of that...
