Any question ask and ill try to help

[Blah]

not neccesarily,

If they were fried you would not be able to turn at all

The reason you cannot counter steer is because of the poorly designed steering system

The servo is puching the steering rod one way or another, then the steering rod puchs the knucle one way or another. if the car is straight u will notice the shaft inside the knucle wil move and will differ the turning radius try this and ull see what i mean

Turn ur car and remote on
hold the car in one hand
u can move the wheel even tho the knucle and steering rod is not moving.

just to show how poor the steering was designed
