In reply to ProLifik, my friend has a sprint 1 and the steering is really bad, he wanted me to take a look at it since i was the more mechanical one out of the two, and i took the servo apart, i i found that one of the gears on the servo had stripped and fallen off, then i told him and i sold him one of my futaba high torque servo, and it's fine now. turning perfectly, so maybe you wanna try that
