  1. Great cyclic servo review by Daniel on 5/20/2015

    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.

  2. I highly recommend this servo if you want the best for your plane. you will not be disappointed with the quality. review by rob on 1/6/2015

    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.
