3-channel servo consistency tester. Connect up to three servos simultaneously to test and compare speed and reaction time without use of transmitter/receiver. Three modes of operation are manual adjust - servo rotates in conjunction with rotation of potentiometer, neutral position - servo centers itself in neutral or middle position, and automatic "window wiper" - servo independently cycles back and forth. Power input 4.8 - 6 Vdc. 1.3" x 1.1" x 0.5" high. Mode select button. Ideal for RC hobbyists.
