Basically, you change the order of the springs to get rid of the slop. The catch is to add some kind of spacing between the first(gold) and second (black) spring, roughly 0.4mm. I used a section of chassis protector for this. Then you just add the third gold spring on top. But this third gold spring is too tight, so you lose almost all the servo-saving features. I had an extra set so I just put another black ring on top instead. For mini, you might be able to get away with just two springs. So far, no slop, and it goes back to neutral fine
