RadioMaster Boxer 2.4GHz 16CH Hall Gimbals Radio Controller with Case, Mode 2 (ELRS) Review (2026)

Who this radio is built for

The Boxer suits FPV pilots ready to commit to a long range, open source radio ecosystem rather than a simpler entry level transmitter, since it ships with EdgeTX firmware and an internal ExpressLRS module built for exactly this purpose. Its Mode 2 stick layout matches what most pilots in the US and most simulator setups expect, so switching between the physical radio and simulator training requires no relearning. It fits both racing and freestyle pilots who value fast, reliable link performance over long distances, and hobbyists who want a radio they can grow into through firmware updates and gimbal upgrades rather than replacing outright as their skills improve.

What the hardware specs deliver

Inside, the Boxer runs on an STM32F407VGT6 processor with 1MB of flash and 192KB of RAM, enough headroom for EdgeTX's full feature set including mixes, telemetry and Lua scripts. The internal ELRS module operates in the 2.400 to 2.480GHz band with a maximum transmit power around 30dBm in international regions, and it can push a 1000Hz packet refresh rate for very low latency control links. Full sized V4.0 hall effect gimbals come standard, with an upgrade path to CNC machined AG01 gimbals for pilots wanting finer stick precision later. A 128x64 monochrome LCD handles the on screen menus, and the radio weighs about 532.5g, powered by either a 2S LiPo pack or two 18650 cells, both sold separately.

Setting it up and using it

Because the Boxer runs EdgeTX rather than a simplified stock firmware, new pilots should expect a learning curve around binding receivers, setting up model profiles and configuring switches, though this same openness is what lets experienced pilots fine tune the radio extensively. The included carrying case is a practical touch for pilots who travel to fly, protecting the gimbals from bumps in a bag. An internal cooling fan on the ELRS version helps the module handle sustained high power transmission without overheating during long flying sessions, and the external module bay supports JR, FrSky or Crossfire modules if you later want to add a second protocol alongside the built in ELRS.

How it compares with other RadioMaster Boxer variants

Against the RadioMaster Boxer Max, which adds carbon fiber construction and AG01 hall gimbals as standard, this ELRS version is the more affordable route into the same core radio, trading some premium materials for a lower price while keeping the same processor and firmware base. Compared with the 4 in 1 multi protocol Boxer variant, this ELRS only version is more focused, foregoing broader receiver compatibility for a simpler, dedicated ELRS setup, a reasonable trade for pilots who have already standardized on ExpressLRS receivers across their fleet. Pilots still flying older FrSky or Spektrum receivers should choose the multi protocol version instead, since this ELRS model cannot bind to those directly.

Verdict for FPV pilots

This is a strong, well specified radio for pilots committed to the ExpressLRS ecosystem, combining hall effect gimbals, EdgeTX firmware and a fast internal ELRS module into one package with a case included for travel. The learning curve around EdgeTX setup is real but pays off in flexibility as your fleet and skills grow. Pilots who already own FrSky or DSMX receivers and do not want to replace them should pick the 4 in 1 multi protocol Boxer variant instead, while anyone wanting the lightest weight and top tier gimbals from day one should look at the Boxer Max.
