I have found it hard to judge a entire brand of servos by one particular model.
I own 5 of these now. I think it is the best servo to handle a single servo steering type setup on the market.
This picture is from 2007:02:20 09:19:05 in the Muggy but the same one is the only one I run in my Xray XT8 now.
I've had lesser Hitechs in for T/B that did not last, in less demanding environments.
I had one 9000s go bad after 3 race days.
