The Overlander Servo Tester, a great tool for testing 1-3 servos at an incredible price!
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
The Servo tester can test up to three servos, ideal for checking consistancy throughout your set up; and can also be used to generate signal for testing ESC's and Electric Motors.
