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.
