I've been reading this thread with interest about the servo saver, as I have never really understood what it is and how it works. Even to the point I wasn't aware that I had one!
Anyways, it turns out that the Thunder Tiger TS-4n comes with one as standard - basically a spring on a vertical rod which keeps to wedge shaped pieces of plastic together (under tension). If these wedges are properly aligned then the steering works, if the car takes a hit strong enough to counteract the tension of the spring then the two wedges pushed away from each other so that they don't sit snugly together anymore and the steering becomes out of whack ... however, this reduces the overall force transmitted to the servo spindle, hence saving it from stripping gears.
That's my understanding.
The trick here seems to be how much tension needs to be applied to the spring so that the wedges cannot be pushed away from each other.
So, if I am correct then I don't understand:
"I prefer mine really tight almost to the point of not having one, almost. As a result I have yet to strip a servo gear. "
- If the tension is really tight then the saver will only come into play (push the wedges away from each other) on a huge impact, and so would be more likely to strip a servo gear for all those lesser impacts?
"You won't have to realign it but it will make it turn in a direction other than your desired direction and you'll have to turn it back. If you can live with that then loosen her up."
- Would this be because the wedges are rotating slightly but not enough to push them completely away from each other, and they return back to their original position (snugly together) due to the tension of the spring?
- When you talk about realigning a servo saver, do you mean getting the wedges to sit back snugly together?
I hope I haven't confused the issue to much. Perhaps different manufacturers implement servo savers in different ways.
