Now you can set up multiple digital servos to the exact same angle. The Servo Protractor is very easy to use and is accurate to 1 degree. Simply take the horn/arm off of your servo, place your servo in the back of the Servo Protractor and align the servo against the aluminum spacer. The spacer is in place so that each servo that you program is set exactly the same. The spacer can also be adjusted for various servos. This unit is recommended for Hitec analog and digital servos; however, it may work with other servos as well... 1 Each Servo Protractor SASPRO$19.99 Copyright © 2003-2008 E-Clec-Tech.
