XRAY - Model racing cars

I use a normal sized ERG-VZ on my electric cars. When I installed the new servo saver on, I found out that when i was tightening the servo screw the whole steering system was binding and when I undid it half a turn the steering linkage would free up. It wasn't long before I noticed that the plastic adapter's hole (K in my case) is too deep and it touches the servo body. So when you tighten the screw, it rubs against the servo body and binds the steering linkage. I got hold of a few 3x5 shims (unfortunately the common 3x6 don't fit) and placed them between the servo shaft and the plastic servo adapter.

So if you are facing problems with your sanwa servo (or any other servo), don't install the plastic shim that is shown on top of page 14 of the manual, (you don't need it) but instead use a few of these shims (I used 0.3mm in total) to set the proper top deck clearance and have a free moving steering linkage.

Probably this has something to do with some drivers experiencing inconsistent steering, or the car not tracking straight, with the new servo saver.

Hope this helps.
