Depends...they pull twice as much power as other servos with the same specs. If terribly lazy design is something that bothers you or if you run electric, you'll want to look at something other than the Savoxes at the high end. I have a Savox 1258 just sitting on my workbench, don't know what to do with the stupid thing. I need to either buy a BEC or sell it cos it just brownouts in every car I've tried so far, causing ESC glitching.
