Looking at Servo City's website I think the Hitec HS-425BB and the Futaba S3001 are the equivalent the S3001 'precision' bearing has dual ball bearings, the 3004 just has one, which would be paired against the Hitec 325HB. The price difference seems to be $1.00 less for Hitec servos against Futaba of the same caliber. It's amazing the crap I'll do (researching servos?) to avoid doing schoolwork! But hey now I know. One day I even went so far as to sand my flight box I cleared off my desk, put on my study light, got out my favorite pencil, put my text and note books on my desk, sat down, and sanded my toolbox. I believe that nothing is harder than opening a textbook (doing the work never seems that bad though. Go figure!)
