Servo Tester

The Servo Tester allows the user to test and exercise servos and
set up a model without requiring the use of a transmitter and receiver.  

It allows the user to control a servo directly, to determine its neutral position and to cycle it automatically for break-in and testing.

The Servo Tester is small in size, low power, reliable and easy to operate.

Controlled by a SCM, it has good stability and high accuracy.

The Servo Tester is adaptable to different power sources: it can use a four-cell dry battery, NiCd or NiMH pack; or it can be connected directly to a UBEC or ESC.

* You may feel that the knob is a bit tight at the neutral position when you turn it - this is not a problem but designed to work this way, so as you can feel where the neutral position is during testing. *
