YOu know to be honest with ya get a ride of that of those cheap servo and get you something with at least 300 oz of torque and that kim hd saver. All i use on my car for steering are over 3oo, break and throttle are at least 200. Savox got some that run good and there cheap. If you bashing use it if you crash use it. if you race and can drive clean then you might be able to get away with it but with a plastic servo that will strippe out really quick. So i would use them. I have the savox 2071 on my t maxx with the kim hd saver and aluminum arm and it work great.
