This is not your average servo. KST spent a long time developing this new servo, and their hard work shows. An impressive servo for many applications, but primarily targeted to helicopter users.

Have these on my Protos, and after nearly 100 flights and 3 major crashes the KST 515mg servos are still going strong. the gears are still smooth, centering is great as well. IMHO, this is the strongest, fastest, most robust servo in this price range.
This is a great servo. Very smooth operation with high resolution. No free play in the gears. Servo arms are a good snug fit.
This high quality servo will improve your flying. I have been using these In one of my pylon racing plane and will be using them in all new planes from now on.
Finally talked my local hobby shop into getting these. Great Servo's
