3CH RC Servo Tester & ESC Speed Controller – CCPM Checker

3-Channel RC Servo Tester & ESC Consistency Speed Controller

Take full command of your RC builds with this compact 3-Channel (3CH) Digital Servo Tester and ESC Consistency Speed Controller. Whether you're fine-tuning a helicopter's CCPM swashplate, calibrating a car's electronic speed controller, or aligning a boat's steering gear, this handy checker makes setup fast, accurate, and hassle-free — no transmitter required.

Key Features

• 3 Operating Modes: Manual (turn knob for precise position control), Neutral (auto-centres servo instantly), and Automatic Sweep (continuous sweep for travel range testing)
• Multi-ESC Consistency Testing: Connect up to three ESCs simultaneously and verify they respond at identical speeds — essential for multi-rotor, heli, and multi-motor RC builds
• CCPM Compatible: Purpose-built for cyclic/collective pitch mixing (CCPM) servos used in RC helicopters
• Universal Compatibility: Works with virtually all standard servos and ESCs for RC helicopters, cars, boats, planes, and crawlers
• Metal Construction: Sturdy metal body built to handle workshop and field use
• Plug & Play: Simply connect via standard JR/Futaba servo connectors — no soldering, no programming
• Powered by External Supply: Accepts 4.2 V – 8.4 V DC input (batteries not included)
• Recommended Age: 14 years and up

Frequently Asked Questions

Q: Does the 3CH RC servo tester work with all brands of servos and ESCs?

A: Yes! This 3-channel servo tester and ESC consistency checker is designed for universal compatibility with standard JR and Futaba-style servo connectors, making it suitable for virtually all major RC brands including servos and ESCs used in RC helicopters, cars, boats, and planes.

Q: Do I need batteries to use this RC servo tester?

A: Batteries are not included and not built in. The tester is powered by an external DC power supply or battery pack in the 4.2 V – 8.4 V range — such as a 2S LiPo pack or a 4-AA battery holder — which you connect via the input port.

Q: What does the ESC consistency function do?

A: The ESC consistency mode lets you plug in up to three electronic speed controllers at once and verify they all respond at exactly the same throttle position. This is critical for multi-motor setups like RC helicopters and multi-rotor drones, where mismatched ESC response can cause handling issues.

Q: What are the three operating modes on this servo tester?

A: The three modes are: Manual — rotate the knob to move the servo to any desired position; Neutral — instantly centres the servo at its midpoint; and Automatic Sweep — the tester continuously sweeps the servo back and forth so you can check its full range of travel without touching anything.
