Servo savers
 

I see them all over ebay, anyone tried them, worth the money??

Plenty of people here on the forum use servo savers and I've seen mixed reviews about using them on crawlers. From what I gather, they're great if your rig repeatedly takes dives and hard hits that can damage servo gears, but I've never used one on a crawler. If you're considering one for the stock servos, be my guest, but I would suggest putting the money toward some metal gear servos instead.

Servo savers are great when used in faster car or truck.
When your basshing session look like this:

I had to upgrade mine in my Losi LST...

But in a crawler I guess that they wont be that necessary.

The best thing to do is going for, is full metal geared servos and maybe aluminium servo horns , I still have to check on that part for my RS10....

Exactly. Aluminum servo horns make a lot of difference. If anyone adds a nice servo/aluminum horn, some aluminum steering knuckles, and a good strong set of steering links, they'll wonder why they didn't do it sooner. The extra stiffness in your steering is nice.

thanks guys, that was kind of my question, saver or better servo.
