This is the STV2.3 servo tester that allows you to test up to 3 servos at a time without the use of a transmitter or receiver. The tester has 3 modes: manual, neutral and automatic. In manual mode, you control the servo/servos directly through the use of the knob. In neutral mode, this determines the neutral position of the servos which is very useful when assembling a new model. Finally, in automatic mode, the servo/servos swing back and forth automatically to both ends of the servos max throw. If you press 'mode' when powering up the servo tester, the throw is set to 150% rather than 100%.
This servo tester offers you compact size, low power consumption, high reliability and easy operation. The servo tester is adaptable to different power sources; it can be used with a 4S dry battery, NiCd or NiMH pack. It can also be connected directly to a UBEC or ESC.
