The Afagobot RC Digital Servo Tester is a powerful and precise tool designed for RC car, truck, helicopter, airplane, and drone pilots who demand accurate servo and ESC performance. With the ability to test up to four servos simultaneously, this compact tester is ideal for setup, diagnostics, and consistency checks at the bench or in the field.

Supporting manual, neutral, and automatic modes, the Afagobot servo tester allows you to quickly verify servo centering, smooth movement, and ESC throttle response. It is fully compatible with analog and digital servos, offering selectable signal frequencies of 50Hz, 125Hz, and 250Hz to match your specific RC setup.

The tester delivers an ultra-precise output signal width ranging from 800–2200µs, accurate to 2µs, making it perfect for detecting subtle servo response changes that cheaper testers often miss. The built-in PPM signal test function with display gives you clear, real-time feedback for advanced troubleshooting and tuning.

Whether you’re dialing in a high-performance FPV drone, setting up a scale RC car, or testing helicopter servos before flight, this Afagobot tester is a must-have tool in any RC hobbyist’s toolbox.
