This device will output the same signal that RC gear uses. Just plug a reciever battery and the device that you want to test into it and turn the knob! No Transmitter needed! The two on-board LED's give feedback on the servo pulse currently being generated.

Practical Uses:
* Test your robot's drive system when your transmitter has been impounded

* Drive your robot or EV scooter without using a transmitter when using any of the most popular motor speed controllers.

* Bench-test your equipment and troubleshoot your system when you need to eliminate possibilities of radio interference or receiver problems.

A must-have for any serious robot or Electric vehicle builder!
