Radiomaster Boxer 2.4G 16ch Hall Gimbals Transmitter 4in1 ELRS CC2500 (ELRS Mode 2) Review (2026)

Confirmed ELRS Mode 2 configuration

Unlike some other Boxer listings that leave stick mode unstated, this version is explicitly sold configured for ELRS in Mode 2, the throttle-on-right layout that the majority of FPV pilots in the United States and many other regions already fly. That removes a common source of confusion when ordering a radio online, since buyers do not need to contact the seller to confirm gimbal wiring before their first bind. The Boxer still includes 4-in-1 multi-protocol and CC2500 support alongside ELRS, so pilots can also bind to older Frsky-protocol receivers from quads built before ExpressLRS became the community standard.

Hall gimbals and stick feel

This Boxer uses RadioMaster's 4.0 Hall effect gimbals as the standard setup, a magnetic sensing design that generally holds its calibration and center point more consistently over years of use than the potentiometer gimbals found in cheaper transmitters. Hall gimbals also tend to feel smoother through their travel, without the slight grittiness some potentiometer-based sticks develop as they wear. RadioMaster does offer the higher-end AG01 gimbal as a separate upgrade for pilots chasing an even finer feel, though the Hall 4.0 units in this configuration are already well regarded within the freestyle and racing community.

EdgeTX firmware

Like other Boxer models, this radio runs EdgeTX, the open source firmware that gives pilots granular control over model mixing, telemetry display, audio warnings, and per-model settings that go well beyond a typical closed-source hobby radio. Configuration and firmware updates happen over USB or by editing files on the radio's SD card, and EdgeTX Companion software lets pilots build and test model setups on a computer before loading them onto the transmitter. The tradeoff of that flexibility is a genuinely deep menu system, which can take new users some time to fully learn even with the stick mode question already settled.

Physical size and power

RadioMaster lists the Boxer's dimensions at roughly 235 by 178 by 77mm and about 532.5 grams, a wide game-controller shape rather than the narrow stick-style body of a traditional transmitter, which some pilots find more comfortable for long flying sessions and others find bulkier to carry. Power comes from a 6.6 to 8.4 volt source, covering either a 2S LiPo pack or two 18650 lithium-ion cells, neither of which ship in the box. A 128 by 64 monochrome LCD displays the on-radio menus, and external JR, Frsky, or Crossfire modules can be added later if a pilot needs another protocol. The larger body spreads switches and trims further apart than a compact radio, which makes them easier to find by feel during a flight without glancing down.

Who should buy this specific listing

This Boxer variant is the more straightforward choice for buyers who already know they fly Mode 2 and want that setting locked in without extra questions before purchase. Because RadioMaster and various resellers list several near-identical Boxer configurations, with the main differences being stated stick mode, protocol emphasis, and included accessories like a carry case, it is worth comparing the exact listing details and seller reputation rather than assuming all Boxer listings are interchangeable. Pilots who want a heavier, feature-dense radio will be well served here, while those wanting something more compact should look at RadioMaster's smaller Pocket-style transmitters instead.
