Description

The RadioMaster Boxer Crush (M2) transmitter combines a powerful STM32F407VGT6 flight controller with an integrated, high-performance ExpressLRS 2.4GHz RF system. This setup delivers ultra-low latency communication, configurable output power, and robust link reliability for competitive FPV racing and long-range freestyle applications. The unit’s electrical design supports a wide 6.6-8.4V DC input range, facilitating use with high-capacity 2S Li-ion battery packs.

Structurally, the Boxer Crush features a durable chassis with user-changeable ergonomic grips and a redesigned SD card slot. The integrated cooling fan ensures stable thermal performance during extended use. Its compact form factor, complemented by the industry-first fabric handle and included signature carry case, offers excellent portability and protection for field operations.

Key Features

  • AG01 CNC Hall Gimbal: Precision-machined aluminum gimbals with Hall-effect sensors provide smooth, accurate, and long-lasting stick input without potentiometer drift.
  • High-Performance Internal RF: Built-in ExpressLRS 2.4GHz module supports packet rates up to 1000Hz, dynamic power adjustment, and robust frequency hopping for maximum link integrity.
  • Extended Battery Life: Oversized compartment accommodates large 2S 6200mAh Li-ion packs (not included), enabling over 20 hours of continuous transmitter operation.
  • Advanced Thermal Management: Integrated cooling fan actively regulates internal temperature, ensuring consistent performance and component longevity during prolonged sessions.
  • EdgeTX Firmware & Hardware: Pre-loaded EdgeTX on a powerful STM32F407 platform (1MB Flash, 192KB RAM) offers extensive model programming, Lua scripting, and telemetry display on the 128x64 monochrome LCD.
  • Enhanced Ergonomics & Portability: Features a low-profile latching SE switch, momentary SF switch, removable T-shape antenna, changeable grips, and a unique fabric carry handle for improved field handling.
  • Comprehensive Connectivity: Includes a standard JR module bay for external RF systems, USB-C with QC3.0 fast charging (2.0A max), and external module power slots in the battery cover.

Applications

  • Primary transmitter for 5-inch and 7-inch FPV racing drones utilizing ExpressLRS receivers for low-latency control.
  • Long-range and cinematic freestyle drone builds requiring reliable telemetry and adjustable RF power output.
  • Multi-model control for fixed-wing aircraft and RC helicopters via the versatile EdgeTX model programming system.
  • Backup or secondary radio for drone racing events, benefiting from the compact size and integrated carry case.
  • Development and beta testing platform for custom Lua scripts and EdgeTX firmware features.

Frequently Asked Questions

What is the input voltage range for the RadioMaster Boxer Crush?

The Boxer Crush operates on a DC input voltage range of 6.6V to 8.4V. This is designed to work directly with 2S Li-ion or LiPo battery packs, with a nominal voltage of 7.4V. The transmitter includes an 18650 battery tray, but high-capacity 2S packs (like 6200mAh) can be used for extended runtime.

Can I use external RF modules with the Boxer Crush?

Yes. The Boxer Crush features a standard JR-style module bay, allowing you to install external long-range systems like TBS Crossfire, Tracer, or ImmersionRC Ghost. The battery cover also includes external power slots to supply these modules directly from the transmitter's main battery.

What firmware does the Boxer Crush run, and is it programmable?

The transmitter comes pre-installed with the full-featured EdgeTX open-source firmware. It runs on a powerful STM32F407VGT6 microcontroller, supporting extensive model programming, Lua scripts for on-screen configuration, and full telemetry display from compatible receivers via the 128x64 LCD screen.

How do the AG01 gimbals compare to standard gimbals?

The AG01 gimbals are CNC-machined from aluminum and use contactless Hall-effect sensors instead of potentiometers. This eliminates stick drift over time and provides extremely smooth, precise control feel. They are widely regarded as among the highest-performance gimbals available for RC transmitters.
