This is a real stong torque servo for being analog,it rivals most if not all digital servos in same size class as far as strength goes,drive train is tight and speed is decent.it costs a little more than most digital/metal servos but worth it,This is a higher quality servo that is very thin and strong and should be considered wen upgrading servos.I got a feelin I'll get a few more of them,not going to replace digitals withem but when strength is important you should try these,you will be impressed with it.I hate to say great but its a Great servo.
