So I purchased the bell crank servo eliminator from rpm. I also ordered the bearings to upgrade the bushings. What I need to figure out now is which servo saver to use
Rpm bell crank-has anyone installed this?

@mrc I posted a quick review over in the Boost forum. I purchased a metal-geared steering servo and installed the stock plastic servo horn. My thought is that the softer plastic servo horn will yield well before the metal gear train of the servo.
In fact, I ran my car at the local track with the RPM bellcrank connected to the stock (plastic geared) servo and only once encountered a problem. After a crash into a wall, the servo horn actually slipped on the servo output spline with no damage to the servo itself. I would suggest you upgrade to the Turnigy 1258TG servo: It's about US$32.00 from HobbyKing.com.
That said, if you DO wish to run a servo saver, you could go with RPM's suggestion of the Kimbrough servo saver. I think you'd want the "small" version to help avoid any clearance issues and having to cut away parts of the chassis. I'd suggest you visit a local hobby shop to check dimensions in person.

What about when the servo isn't connected to anything? Just a servo horn installed? Does it center then?
If so, double check all the bellcrank screws to make sure they're not too tight. Also check other components in the steering to make sure nothing is binding.

Well, try disconnecting the servo from the steering, leaving the servo horn/servo saver in place, and use your radio to actuate the servo. Does it center after turning full right and left?
