The ToolkitRC ST8 Advanced Multi-Servo Tester boasts a wide array of features usually reserved to professional test equipment.
The unit can be used to run 4 servos independently or control 8 servos from a single input. Servos can be controlled using pre-set control modes or precisely via a scroll wheel. They can also be driven from an external input signal, with support for PWM, PPM, or S.Bus signals.
There are various measurement modes available, which allow you to test things like the response speed of servos and current draw. The latter is useful as you can then be sure your UBEC is sufficient to supply the required amp load, or it could allow you to fault find; say for example detecting a high current load caused by a stuck control surface. Best still this information is clearly visualised on the LCD display.
Input power to the ST8 can be 7-28V and connected via the XT60 socket. The unit powers the servos and the output voltage can be adjusted from 5V to 28V to suit standard and high voltage servos.
Features:
- Data analyzer device 8-channel signal output, current measurement, curve display, and other functions.
- 4 channels of programmable independent signal, 8 channels of signal output, the accuracy of 1 ms.
- Current acquisition on 4 channels with accompanying curved data display.
- Multiple measurement modes (speed, count, step, linear).
- Output PWM signals with a period of 33 to 1000 Hz.
- A variety of signal trigger sources (internal, buttons, knobs, external sources).
- The external input signal supports PWM/ PPM/ SBUS with an accuracy of 1 ms.
- Drive the servo with a maximum load of 100W.
- USB firmware update, easy to operate.

Questions and answers of the customers

Top tip: Use a servo / ESC when wiring up your motors, it’s a lot quicker than plugging in your radio control equipment. If you are wiring up an octocopter you can soon end up with a nest of wires, even a quadcopter can be pretty bad. If you haven’t labeled the wires individually, you can easily forget which each wire relates to. With an inexpensive servo / ESC tester you can quickly test which wire connects to which motor and then test whether the spinning direction is correct. Remember if the motor spins in the wrong direction, all you need to do is swap the positions of 2 out of the 3 ESC output wires.
