With this you can do the following without using your radio:
- Run electric motors
- Test servos
- Know at what receiver pulse width your motor starts
- Know at what receiver pulse width your motor is fully on
- Match your transmitter throttle channel to your speed control

This Servo Tester can be used with or without an external receiver
nicad battery pack. You will find two radio cables on the tester.
The three wire cable goes to your servo or Electronic Speed
Control. If your speed control has a BEC circuit, it will not be
necessary to use a separate 4 cell receiver battery. If your
speed control has no BEC circuit or if your are testing servos,
you will need to use the receiver battery. Connect the receiver
battery to the two wire radio connector.

The Model 105 Servo Tester operating mode allows user to adjust servo
signal from one millisecond (low throttle) to two milliseconds
(high-throttle).
