ToolkitRC ST8 Multi-Servo Tester

The ToolkitRC ST8 is a bench servo tester that drives up to four servos at once and doubles as a receiver signal reader. It suits fixed-wing, helicopter and RC car builders setting up control surfaces and linkages, and UAV builders checking servos before installation.

Key features

• Four servo outputs (S1-S4) powered at an adjustable 5.0-8.4V with up to 4A shared, so high-voltage servos run at their real voltage

• Signal output from 100 to 2900us at 33-1000Hz, covering analog, digital and high-frame-rate servos

• S5 input reads PWM, 8-channel PPM and 16-channel SBUS for receiver testing

• Main output port passes 5-28V at up to 10A

• 2.4-inch colour display, firmware updates over Micro USB
