RadioMaster Boxer 2.4GHz 16CH Hall Gimbals Radio Controller - Compact

Our review of the RadioMaster Boxer finds it aimed at pilots who want a compact, feature-rich transmitter without sacrificing control quality; the single biggest reason to consider it is the combination of full-sized Hall effect gimbals and multi-protocol RF flexibility, which makes setup for different models fast and reliable. The Boxer balances portability and comfort through a thoughtful ergonomic layout and an oversized battery bay that accepts a 2S 6200mAh pack for extended sessions, while the EdgeTX firmware and optional ExpressLRS provide modern, low-latency performance.

Key Features

• Full-size V4.0 Hall gimbals: Provide precise, smooth stick response for accurate control and reduced drift during long flights.
• Internal RF options: Available with ExpressLRS or 4-in-1/CC2500 MPM modules to support multiple receiver protocols without external adapters.
• Powerful processor: The STM32VGT6 with 1MB RAM keeps EdgeTX and complex mixes running responsively under load.
• Oversized battery compartment: Fits a 2S 6200mAh pack for up to extended durations, reducing the need for frequent battery swaps.
• Compact ergonomic design: Measures 23517877mm and balances portability with comfortable hand positions for long sessions.
• Standardized control layout: A familiar RadioMaster button layout and JR module bay make it easy to transition from other transmitters.

Who It's For

The Boxer is well suited for hobby pilots and FPV racers who travel or attend field sessions and need a compact radio with high-quality Hall gimbals and multi-protocol support; its internal module options and EdgeTX firmware make it versatile for pilots who own several models and receiver types. The oversized battery bay and choice of RF modules also appeal to those who value long runtimes and low-latency links, particularly when choosing the ExpressLRS version.

Pilots who should look elsewhere include those who require isolated large-console ergonomics or integrated telemetry displays beyond what a compact transmitter provides. Also, if you demand premium aftermarket gimbals out of the box, be aware some users report mixed impressions of the stock gimbals and may prefer upgrading to AG01 CNC Hall gimbals.
