3-Channel Servo Tester / ESC Controller – 4.8–6V

The 4.8–6V Multi Servo Tester is a compact diagnostic tool designed for testing and calibrating RC servos and electronic speed controllers (ESC). It features three operating modes—manual, neutral, and automatic sweep—allowing precise evaluation of servo response and performance. The device supports simultaneous testing of up to three servos or ESCs, enabling quick comparison and system validation. Built for stable operation with LED status indicators, it ensures reliable feedback during testing. Ideal for robotics development, RC systems, and embedded electronics projects.
