JP Hobby Servo / Retracts / MotorTester

JP Hobby Servo and Retracts Tester

The JP All-Metal Digital Servo Tester is a professional-grade tool designed for testing and calibrating servo motors, electronic speed controllers (ESCs), retractable landing gear, and other RC applications. It is built for durability and precision, making it ideal for both hobbyists and professional technicians. With an intuitive three-level indicator design and a robust metal housing, this tester ensures efficient and reliable performance in various scenarios, including routine maintenance, troubleshooting, and product lifespan evaluation.

Caution! Never connects retract directly to the servo tester. The retracts must always be connected to their own controller, and only the controller should be connected to the servo tester.

Key Features

• Wide Voltage Compatibility: Supports an input voltage range of DC 5V–16.8V, making it suitable for a variety of RC models including airplanes, cars, boats, and robotics.
• Digital Display & LED Indicators: Clear digital readout and intuitive LEDs provide real-time feedback for easy operation, even for beginners.
• PWM Signal Adjustability: Achieve precise control with a 0.9ms~2.1ms PWM signal range, ensuring responsive throttle adjustments.
