Who needs a servo saver?

[harvey]

I have heard lots of drivers on here tout the advantages of ditching the servo saver, and I see my World's kit comes without. With the specs on servos going through the roof, I'm not surprised, but still nervous of damaging parts. Is there (in the experience of our members) a safe threshold that one could recommend for saver-less operation? Put another way, what numbers would one feel comfortable using no servo saver? Metal gear only I'd assume, but how about 85oz/in? Servos in that range seem adequate for my RC10 buggies with a servo saver, but holding power won't help you if the impact goes straight to a gear tooth (I'd bet).
Or is this strictly a track thing where you're waiting for that one bad impact that could roast even the most powerful servo?

Unless you are a very clean driver I would run a servo saver. Personally I don't use one in my T4.2 and havn't had an issue (JR Z9100S). While the titanium gear servos seem great titanium is quite brittle and can shear off teeth. I'd stick to steel gears if you can, brass would be second but brass is soft.

it aint the torque numbers that justify the absence of servo saver - it's the teeth's material

(lotsa holding torque + weak material = broken gear)
