Don't skimp on servos these little devices are super important but setup is even more important. If this isn't done correctly it doesn't matter which servo you own it will fail eventually. Savox, futaba and hitec have treated me right. I've been running Savox for over a year with out failures HV. the 79xx series hitecs have been solid. Futaba BLS series are also solid expecially with futaba radio gear. I've also been running the 7955 for years I mean years only recently one failed which was in service for three years definitely can say I got my money's worth.
Also customer service is important Hitec is the best. Savox, haven't used as of yet and futaba can be a little picky but they did what a customer would expect from my personal experiences.
Me next purchase will be KO Rsx servos I've had very good feedback from fellow racers about these their quite expensive but as I stated you pay for great performance and CS.
