Very good High Torque servo. Comes with all neccesary parts, Servohorn, screws, etc. Very easy to install, just plug the cable into your receiver and it works right away. Once connected to the chassis it reacts to the controls VERY precise, and even the smallest little turn to the wheel on the remote moves the servo. For the price, it is definitely worth buying. Once again, Futuba did a great job in building the high quality piece of technology.
