Description

The RadioMaster Boxer Crush (M2) transmitter consolidates advanced radio control hardware into a portable form factor. Its core is built around the powerful STM32F407VGT6 microcontroller, providing ample processing headroom for the feature-rich EdgeTX operating system and managing the high-speed communication of the internal ExpressLRS module. The integration of this module eliminates the need for an external transmitter, offering a clean setup with professional-grade long-range and low-latency performance.

Durability and user experience are central to the design. The AG01 CNC aluminum gimbals employ Hall-effect sensors for unparalleled accuracy and longevity, while the chassis incorporates an internal cooling fan to maintain optimal module temperature during extended use. The transmitter supports a wide 6.6-8.4V input range, accommodating high-capacity 2S LiPo or dual 18650 Li-ion configurations, and features QC3.0 fast charging via its USB-C port for minimal downtime.

Key Features

  • High-Performance RF Core: Built-in ExpressLRS 2.4GHz backpack module delivers ultra-low latency, long-range control, and a 1000Hz refresh rate, with software-adjustable RF output power.
  • Open-Source Firmware Platform: Pre-installed with EdgeTX, offering unparalleled customization of mixes, scripts, telemetry, and model setups via a companion PC application.
  • Professional Gimbal Assembly: AG01 CNC-machined aluminum Hall-effect gimbals provide smooth, precise, and magnetically-sensed stick input without potentiometer wear.
  • Extended Operational Endurance: Oversized battery compartment supports a 2S 6200mAh LiPo pack (not included) for up to 20 hours of use, with QC3.0 fast charging for rapid replenishment.
  • Enhanced Thermal Management: Integrated cooling fan ensures the internal ExpressLRS module maintains stable performance and component longevity during intense operation.
  • Modular Expansion & Portability: Standard JR-formatted external module bay for adding Crossfire, FrSky, or other protocols, paired with a fabric carry handle and included signature hard case.
  • Ergonomic & Customizable Design: Compact form factor with changeable side grips, a 6-position flight mode switch, low-profile latching/momentary switches, and a redesigned SD card slot.

Applications

  • Primary transmitter for long-range and low-latency FPV drone builds utilizing ExpressLRS 2.4GHz receivers.
  • Compact and portable control station for freestyle, racing, and cinematic drone pilots who prioritize ergonomics and travel size.
  • Versatile radio platform for multi-model RC enthusiasts, supporting external modules for Crossfire, FrSky, and other protocols in addition to the internal ELRS.
  • Ideal for pilots transitioning from gamepad-style controllers seeking the full customization of EdgeTX without the bulk of a full-size transmitter.
  • Robust ground control station for DIY UAV and ArduPilot/INAV-based autonomous vehicle projects requiring reliable telemetry and switch control.

Frequently Asked Questions

What type of batteries does the RadioMaster Boxer Crush use, and are they included?

The Boxer Crush requires a 7.4V 2S LiPo battery or two 3.7V 18650 Li-ion cells to operate within its 6.6-8.4V input range. The transmitter includes an 18650 battery tray, but the batteries themselves are not included. It supports QC3.0 fast charging via the USB-C port for the installed pack.

Can I use other long-range systems like TBS Crossfire with this transmitter?

Yes. While the Boxer Crush (M2) ELRS version has a built-in ExpressLRS module, it also features a standard JR-formatted external module bay on the rear. This bay is fully compatible with TBS Crossfire, FrSky, and other JR-style transmitter modules, allowing you to use multiple RF protocols simultaneously or switch between them.

How do I update the EdgeTX firmware and ExpressLRS module on the Boxer Crush?

Updates are performed via the included SD card and USB-C connection. Use the EdgeTX Companion PC software to download and flash the latest EdgeTX firmware for the transmitter. The internal ExpressLRS module is updated separately using the ExpressLRS Configurator tool, which can also be accessed through the EdgeTX Lua scripting interface on the radio itself for wireless updates.

What is the advantage of the AG01 Hall-effect gimbals?

The CNC-machined AG01 gimbals use Hall-effect magnetic sensors instead of traditional potentiometers. This design eliminates physical contact and wear on the sensing elements, resulting in perfectly smooth control, infinite resolution, and absolute long-term accuracy without the jitter or drift associated with worn pots. They are considered a premium upgrade for precise flight control.
