3CH Digital Servo Tester And ESC Checker With CCPM Consistency Speed Controller And 4 Cell AA Battery Holder Case For RC Helicopters And Cars Includes Manual Neutral And Auto Wiper Modes Aluminum Alloy Shell

3-Channel Servo Tester & ESC Checker with CCPM, AA Holder
✔️ 3-channel tester supports 3 servos/ESCs, CCPM, and auto/neutral modes

Designed for RC hobbyists, this 3CH servo tester functions as an ESC checker and CCPM simulator. It’s ideal for RC helicopters and cars, enabling quick timing checks, neutral positioning, and wiper-style movement tests without needing a transmitter and receiver.

✅ 3 channels can test 1-3 servos or ESCs simultaneously
✅ CCPM helicopter support for servo selection and alignment
✅ Manual, neutral, and automatic window-wiper modes for varied motion tests
✅ Also functions as an ESC signal generator to test motors without TX/RX
✅ Aluminum alloy shell is durable and lightweight; compact: 48mm x 42mm x 17mm
✅ Input 4.8-6V DC; output 15mA; signal timing around 1.5ms +/-0.5ms
✅ Includes 4-Cell AA Battery Holder for quick power supply

💡 What is a 3CH servo tester used for in RC helicopter and car build workflows?

It’s a handy tool that helps you verify servo timing and ESC behavior without a full radio setup.

- Testing servo response times across multiple channels
- Checking CCPM servo synchronization for helicopter models
- Comparing ESC input/output timing to tune performance
- Debugging motor systems safely without a transmitter
