I don't have any direct experience with the BSx servos, but I do know that the new RSx servos will look/feel 'notchy' when you move through the steering range while the car is on the bench. It almost looks like the servo 'steps' through the full throw range, if that makes sense. I asked Robert about this at Worlds when I noticed that my RSx2 was doing this, and he told me it is expected and exactly what the servo should be doing. The car will feel perfectly normal while on the track - it is only noticeable while the car is on the bench. Not sure if this is what you are experiencing, but just wanted to mention it.
I would recommend sending an email to Robert @ KO using the support email address noted above (email@example.com). If you show him the video and describe the symptoms, I am sure he will let you know what he thinks.
