I have numerous of these HP metal BB analog servos in my 60 size planes. Use them for throttle, rudder amd elevator applications and never a glitch, never any problems after 16 flights to date. If you can get these when on sale, buy a few and try'em out, I think you'll be happy with the performance as I am. Great deal Hobby People! (Posted on 3/18/12)

Great steering servo. Replaced a 645 servo in my slash and it works as well and for $10 less. Nice servo. (Posted on 9/11/11)

I bought 6 of these servos for a Seagull Edge 540 68" wingspan. The servos has plenty of power, speed but centering is not the best. I always have to be on the sticks also has some slop on the gears. I guess for the price are ok but I wish I had kick it up a notch. (Posted on 9/11/11)
