thats a good place to get consistent stopping points,my servo is high voltage and strong,but sometimes the speed of the servo causes the inside wheel to over steer.
I dont see what adding washers under the bolts on the steering links does to adjust bumpsteer,no matter how many washers you add there its just pushing the head of the bolt further away and doesnt move the height of the steering turn buckle?
also what is the servo mount for in the rear of car,I put a extra hobby wing pro esc back there on top of it ,it looks like if it where cut out that esc would fit there perfect,and get more weight towards the rear of the car, I thought it was not to cool to have the boxed in servo mount in the front for steering also,I use futaba hv servos that are a bit to wide to fit in it,that was a pain to dremel out.
