Servo Buddy is a compact, user-friendly tool designed for RC enthusiasts and hobbyists who want a simple, reliable way to test and center servos and ESCs. Whether you’re working on an RC plane, car, or custom robotics project, Servo Buddy makes the process effortless with intelligent features that make using it simple, fast and reliable.

The Servo Buddy is launching as a limited run of 50 numbered units, designed to involve the community in its final development. Each unit is assembled in the HackMakeMod workshop and has an acid etched metal insert showing your unique number. Here’s how it works and why it’s a win-win for everyone.

This limited run is about more than just testing. It’s about building a tool with the community, for the community. Your input helps make Servo Buddy the best it can be… and we want you to be part of the journey!
