Xiangtat RadioMaster Boxer 2.4G 16ch Hall Gimbals Transmitter ELRS 4in1 CC2500 Review (2026)

What the RadioMaster Boxer offers

The Boxer is built around full-size hall effect gimbals as standard, which use magnetic sensors rather than potentiometers and hold their calibration better over years of use compared to cheaper radios. It runs EdgeTX firmware and supports up to 16 channels depending on the receiver, giving room for auxiliary switches like arm, beeper, and turtle mode alongside the core flight channels. The transmitter measures roughly 235 by 178 by 77mm and weighs about 532.5 grams, a comfortable size for extended flying sessions without feeling front-heavy in the hands even after long practice sessions.

ELRS and 4in1 combined support

This version combines ExpressLRS support with a 4in1 CC2500 multi-protocol module, meaning one radio can bind to ELRS-equipped quads as well as a wide range of other protocols like FrSky and Flysky through the internal 4in1 module. That flexibility matters for pilots who own a mixed fleet of drones built over several years on different protocols, since it removes the need to carry multiple transmitters or swap external modules constantly. ExpressLRS transmitting power reaches up to 30dBm internationally, or 20dBm under EU LBT restrictions, which is on par with dedicated ELRS-only radios in the same price range, and switching between the two internal modules is handled from the EdgeTX menu rather than requiring any hardware changes.

Display, power, and everyday use

The Boxer includes a monochrome LCD display for navigating EdgeTX menus and monitoring telemetry, along with a processor built on the STM32F407 chip that has enough flash and RAM headroom for EdgeTX's more advanced features like Lua scripts and custom telemetry screens. It runs on a 2-cell lithium polymer pack or two 18650 cells depending on the version purchased, with batteries typically not included, so factor in a battery purchase if the seller's bundle does not clearly state one is included. The layout also mixes momentary, latching, and toggle switches around the case, giving room to assign arm, mode, and beeper functions without hunting through a cramped switch panel.

Why this particular listing needs a closer look

This listing is sold through a third-party seller rather than directly from RadioMaster or a major FPV retailer, and the title does not specify which control mode, gimbal spring tension, or exact case contents ship with this unit. RadioMaster and its authorized resellers sell the Boxer in multiple configurations, including different modes and an optional carry case, so buyers should message the seller to confirm mode, included accessories, and battery before ordering, and should also clarify how warranty claims are handled given the third-party channel, since that process can be less direct than buying from an authorized RadioMaster reseller. Comparing the listed price against RadioMaster's own store for the same configuration is a reasonable way to judge whether the convenience of this listing is worth any premium.

Who should consider this radio

The Boxer's hardware suits intermediate to advanced FPV pilots who want one radio that can bind across ELRS and legacy protocols without swapping modules, and who value hall gimbals that will not need replacing after heavy use. It is a reasonable step up from an entry-level radio for someone building out a mixed fleet of quads. Given the ambiguity in this specific listing, buyers who want certainty on mode, accessories, and support should compare pricing against RadioMaster's own store or a known FPV retailer selling the same hardware with clearer listing details and a more straightforward return path.
