What is enough spring tension for servo saver?

[mrluckies]

I have a Losi LMT, but this will apply to a lot of other trucks and crawlers. How do you know when you have a strong enough, but not too strong servo saver?

I broke a few servos on the lmt and finally bought a reefrc raw 500 for it. I also bought a treal servo saver. It comes with a standard and harder spring. Plus you can tighten the nut a couple turns to increase the tension.

So how do I know if I need the standard or higher tension spring? And how do I know when the spring tension nut is tight enough?

If the spring tension is too loose, it won’t protect the servo because it will immediately go to the end of travel and the. Transfer tha force to the servo.

If it’s too tight, it’s like not having a servo saver at all.

Any suggestions?

Unfortunately my answer probably won't be as precise as you'd like, as this is more of a "trial and error" thing.

If you're more concerned with saving servos than you are with steering performance, then start with looser rather than tighter. Over time, you can crank it down more if you feel you're not getting enough steering.

But I'd start with the truck on its wheels and stationary. Tighten down the servo saver until you can get full steering both directions without activating the servo saver. If you want to play it extra "servo-safe," loosen it a 1/4 or 1/2 turn from there. That should favor servo protection over steering performance.

Then as you drive it, and see if you want faster, or more steering, tighten it up a 1/2 turn at a time.

I’m definitely more concerned about saving the servo. I was concerned thst the servo saver could be too soft and not sure what to look for. Thx!

You could also look for a servo rebuild kit. Its just a matter of swapping the gears and pins and much cheaper than a new servo. I imagine not every model of servo out there will offer these kits though.
