3-Channel CCPM Servo Tester ESC Speed Controller

The 3-Channel CCPM Servo Tester is a compact, indispensable bench tool for RC hobbyists, drone builders, and robotics enthusiasts who need to quickly test, calibrate, and compare servo motors and electronic speed controllers (ESCs) without connecting a full transmitter and receiver setup. Simply power it from any 4.8–6V source, plug in your servo or ESC, select your mode, and get instant, live feedback in seconds.

The tester supports up to three servos or ESCs simultaneously through three standard 3-pin signal output channels (Signal / Power / Ground), making it ideal for testing CCPM helicopter servos for consistency and synchronisation, verifying ESC arming sequences, checking servo centre points, and comparing reaction times across multiple units side by side. Three onboard LED mode indicators — Man, Neutral, and Auto — clearly confirm the active test mode at a glance.

Three operating modes cover every testing scenario: Manual mode allows the onboard adjustment knob to be turned to manually sweep the servo or ESC output from minimum to maximum, checking reaction speed and mechanical range; Neutral mode instantly centres all connected servos at the 1.5ms mid-pulse neutral position — ideal for mechanically aligning control surfaces and linkages; and Automatic (window-wiper) mode continuously sweeps all connected servos back and forth through their full angular range without manual input, stress-testing travel limits and checking for binding. Output PWM signal ranges from 900µs to 2100µs at a 50Hz refresh rate, compatible with both analogue and digital servos.
