I now recommend and only use the ProTek servos now. The 160SS is simply perfect. I have $230 Futaba OS Speed servos sitting in my pit bag now. They just aren't as fast and smooth as the ProTeks, plus I feel more connected running them. I even ran the Futaba servos on SR mode with my 7PX, still not as good as the Proteks. I have at least a dozen Savox, Xpert, MKS servos setting around. I throw them in when I sell a car. They don't even compare to the ProTeks. No I am not sponsored by them, just love the servos.
