Description

The RadioMaster Boxer 4IN1 transmitter delivers professional-grade control in a portable form factor. Its core is the powerful STM32F407VGT6 microcontroller, providing ample processing headroom for complex model configurations and telemetry on the EdgeTX open-source platform. The integrated 4-in-1 RF module offers exceptional versatility, allowing pilots to bind with virtually any 2.4GHz receiver protocol without the need for external hardware.

Engineered for comfort and durability, the Boxer features full-size, adjustable Hall effect gimbals known for their precision and longevity. The chassis incorporates thoughtful ergonomics, a unique fabric handle for easy transport, and a logical button layout for efficient in-flight adjustments. With support for high-power RF output up to 20dBm and fast USB-C charging, it is built for extended flying sessions and reliable performance in demanding FPV and drone piloting environments.

Key Features

  • Universal 4-in-1 RF Core: Internal multi-protocol module provides native support for ACCST, ACCESS, DSMX, AFHDS, and other major 2.4GHz protocols.
  • High-Performance Processing: STM32F407VGT6 processor ensures smooth, responsive operation with EdgeTX for advanced scripting and telemetry.
  • Precision Hall Gimbals: Full-size, adjustable gimbals with magnetic sensors offer exceptional resolution and repeatable control inputs.
  • Extended Range Capability: Configurable RF output up to 20dBm (100mW) provides a strong, stable link for mid-range FPV and drone applications.
  • Rapid Charging & Power Management: USB-C port with QC3.0 support enables fast charging of the internal 2S Li-ion or optional 18650 cells.
  • Ergonomic & Portable Design: Compact footprint, textured grip, and integrated fabric handle optimize comfort and portability.
  • Expansive Control Interface: Includes a 6-position switch, new latching SE and momentary SF switches, and a 128x64 monochrome LCD.
  • External Module Ready: Battery cover features power slots for adding high-power ELRS, Crossfire, or other external long-range modules.

Applications

  • Primary transmitter for FPV racing and freestyle drones using ExpressLRS, FrSky, or other 2.4GHz receivers.
  • Versatile control for fixed-wing aircraft, gliders, and scale models requiring multi-protocol compatibility.
  • Compact radio for drone pilots who prioritize portability without sacrificing gimbal quality or system features.
  • Ideal for pilots transitioning to EdgeTX who need a powerful, universal radio for a mixed fleet of models.
  • Ground control station for long-range UAVs when paired with an external high-power module (e.g., 915MHz ELRS).

Frequently Asked Questions

What protocols does the RadioMaster Boxer 4IN1 internal module support?

The internal 4-in-1 multi-protocol module (MPM) supports a wide range of major 2.4GHz protocols, including FrSky ACCST D8/D16 and ACCESS, FlySky AFHDS and AFHDS 2A, Spektrum DSM2/DSMX, Futaba SFHSS, and many others. It is flashed with FCC-certified firmware, providing universal compatibility for binding with most common RC receivers without needing an external module.

What is the maximum RF output power, and can I use an external module?

The internal 4-in-1 module can be configured for output power up to 20 dBm (100mW). For extended range or different frequency bands, the Boxer is ready for external modules. Its battery cover includes dedicated power slots, allowing you to install and power high-power ExpressLRS, TBS Crossfire, or other long-range transceiver modules via the external JR-style bay.

What batteries are compatible, and how do I charge the transmitter?

The Boxer operates on 6.6V to 8.4V DC, compatible with an internal 2S Li-ion pack or two 18650 cells using the included tray. It features a USB-C port with QC3.0 fast charging support, capable of up to 2.0A input for rapid replenishment. You can charge the installed battery directly via USB-C without removing it.

Is the EdgeTX firmware on the Boxer user-upgradable?

Yes, the RadioMaster Boxer comes preinstalled with EdgeTX but is fully user-upgradable. You can update the firmware via the standard EdgeTX Companion software on your computer, connecting the transmitter via USB-C. This allows access to the latest features, bug fixes, and Lua script capabilities for advanced model configuration and telemetry.
