April 16, 2010Application(s): single steering servo for Revo 3.3
Comments: works OK though it sounds like it strains as it reaches it's end points. It's reasonable fast and when the truck is moving it does a good job (though not as good as the Hitec 985MG i've got in another Revo. THAT is a kick a$$ servo)
