Is there a" baseline" for torque and speed before it becomes over kill? Is there a" rule of thumb" as far as steering vs throttle? Servos seem to be a lot like engines; they generate a lot of opinions. I am looking at going with a Savox SC-1258TG using a life battery in a RC8 buggy or maybe the 1257 which is a little faster. I currently use a JR Z900T for steering which is probably over kill for a buggy. The brake/throttle is so old the label is gone. All I know is it is a HiTech that is about 3 years old. Never had any issues with servos. Just thought it is time to replace them. Savox has a really good promo right now!
