Actually my fast one works great, my torquey one is junk.
I think they have the same exact motor, just different gearing.
So I'm going to chalk it up to poor quality control and maybe try a 3rd one. This one just feels chunky while rotating it, even after cleaning the gears up and rebuilding it and removing oring. It's as if it is trying to find center and just vibrates like crazy. Not noticeable with wheels on the ground though, and car drove fine. But the servo shaking like that will probably eat the gears quickly.
