RadioMaster Boxer 2.4GHz 16CH Hall Gimbals Radio Controller with Case, Mode 2 (4-in-1 Multi-Protocol) Review (2026)

Who it is for

This version of the Boxer is built for pilots whose fleet is not all one protocol, such as someone with a mix of Frsky, Flysky, or DSM receivers on older builds alongside a couple of newer quads, plus micro whoops that bind on yet another protocol entirely. The internal 4-in-1 module covers CC2500, NRF24L01, A7105, and CYRF6936 chipsets, which between them handle a wide range of budget and hobbyist receiver protocols without needing an external module plugged into the back of the radio. Pilots who fly exclusively ELRS quads will get less value from this specific version, since ELRS is not one of the built-in protocols here; the separate ELRS edition of the Boxer covers that case instead and is worth comparing directly against this multi-protocol model before buying.

Build and gimbals

The Boxer uses a game-pad style body that is noticeably larger than pocket transmitters, with room for a proper battery compartment and a more substantial grip than compact radios offer. Radiomaster fits it with fourth-generation hall gimbals as standard, which is the same class of gimbal used across the brand's higher-end radios and holds centering accuracy well over years of use compared with cheaper potentiometer sticks. A monochrome LCD runs the EdgeTX menu system, and the radio ships with a carrying case, which is a genuine convenience for a transmitter this size since a bare Boxer does not fit as easily into a generic bag pocket the way a smaller radio does. Build quality at this price point is generally regarded as a step up from entry-level plastic transmitters.

Power and protocols

Because the internal module handles four separate legacy protocols rather than one modern one, the Boxer 4-in-1 can bind almost anything a pilot is likely to already own that is not ELRS, which is a real advantage for anyone maintaining a mixed fleet built up over several years of the hobby. Output power on CC2500 and the 4-in-1 protocols tops out around 20dBm, which is standard for these protocol types and matches what dedicated single-protocol radios using the same chips deliver. The battery compartment is sized for a 2S pack, giving long flying sessions between charges compared with radios that only fit a single-cell internal battery, and QC3.0 fast charging cuts down on downtime between sessions.

Where it falls short

The obvious limitation is that ELRS, currently the most popular modern protocol in the FPV hobby, is not one of the four protocols built into this version, so pilots who want to fly ELRS quads with this radio need to add an external ELRS module in the back bay rather than binding natively. That adds cost and a small amount of bulk that the ELRS version of the Boxer avoids entirely. The body size that helps with battery capacity and grip also means it does not slip into a small bag the way a Pocket or other compact radio does, so pilots who value portability over protocol breadth may find the size a tradeoff worth weighing before choosing this model over a smaller transmitter.

Bottom line

For a pilot with a genuinely mixed fleet of protocols, the Boxer 4-in-1 is a sensible way to consolidate several old single-protocol radios into one transmitter with modern hall gimbals, EdgeTX, and a case included. It is less compelling for someone who flies ELRS exclusively, since the dedicated ELRS version of the same radio removes the need for an external module and is the more direct choice in that case. Anyone deciding between the two should confirm which protocols their current and planned receivers actually use before committing, since the hardware difference between the two Boxer variants is specifically about which radios they can bind to without extra parts.
