GT Power Servo & ESC Tester – Precision Calibration Tool for RC Hobbyists | Buy at Grayson Hobby

The Servo Tester from GT Power, now available at Grayson Hobby Shop, is a versatile tool designed for both servo and ESC testing, making it essential for RC enthusiasts. With its robust metal casing, this updated tester offers enhanced durability, preventing damage in gear bags. It’s ideal for troubleshooting by allowing users to bypass the radio and directly test servos and ESCs, ensuring correct calibration and centering, which is particularly useful for gyro receivers and eliminating issues like unintended trim adjustments.

In addition to servo testing, this tool helps with speed control calibration, offering easy adjustments to throttle positions without relying on the radio, which can sometimes lead to errors. The tester includes multiple modes—manual, neutral, and sweeping—to check for issues like stripped gears or binding. This reliable, budget-friendly tool is a must-have for safe and accurate setups, available both in-store and online at Grayson Hobby Shop.
