Introduction

HDZero Radio is a new compact ExpressLRS radio designed to make ELRS simple, fast, and usable without extra gear.

The core idea is straightforward: ELRS is extremely powerful, but it can be confusing to bind and configure in the field. HDZero Radio solves this by putting the controls pilots actually use directly on the radio, with clear menus and dedicated shortcuts.

With built-in 250 mW ELRS, full onboard configuration, and a smooth OLED interface, HDZero Radio removes the need for phones, laptops, or external tools during setup and flying.

The HDZero radio is well suited as both a starter radio and a compact travel or secondary radio. This does not run EdgeTX, instead of a general-purpose OS, we built a slim, FPV-first interface that focuses on the things pilots actually change day-to-day.

The HDZero Radio makes it easy to share the FPV hobby with others using its built-in Trainer (Buddy Box) support. With a standard DSC trainer jack, an instructor can safely hand control to a student while retaining instant override. This makes learning faster, safer, and far less intimidating for new pilots.

Why it's interesting:

  • 250mW ELRS with full configuration onboard
  • One-touch button opens the ELRS configuration menu
  • Packet rate, telemetry, output power, and VTX settings in one place
  • Press-and-hold shortcut for ELRS binding
  • Full ELRS menu still available for advanced users
  • Built-in OLED with smooth 50 fps UI, including live stick visualization
  • VTX Admin to change band, channel, and power without touching the aircraft

Where it really shines:

  • Excellent starter radio for pilots learning ELRS
  • Ideal second or travel radio — compact, lightweight, sticks stow inside, hard case included
  • Full ELRS control in the field without a phone or laptop
  • Great buddy-box radio for teaching using the trainer jack

More highlights:

  • ELRS Backpack support to sync video channels between drone and goggles
  • Bluetooth ELRS joystick mode for wireless simulator use
  • Trainer jack also supports head tracking from compatible goggles
  • Up to ~10 hours of battery life at 10 mW

HDZero Radio does not run EdgeTX. To target entry-level pricing it uses a purpose-built, FPV-first interface instead of a general-purpose operating system. This allows faster access to the settings pilots change day-to-day, while keeping the radio simple, reliable, and affordable.
