Overlander's Servo tester can test up to three servos, it is ideal for checking consistency throughout your set up and can also be used to generate signal for testing ESC's and Electric Motors.

The Servo tester features three modes -

1. Manual - Servo position controlled directly by position of control knob
2. Neutral - Servo resets to neutral/middle point
3. Automatic - Servo swings back and forth in a 'window wiper' motion
