The RadioMaster Boxer Max is a full-size hobby radio with an internal ExpressLRS 2.4 GHz module, so you do not need an external transmitter module to fly modern long-range links. This version is the M2 model with AG01 CNC aluminium Hall-effect gimbals, and the case is finished in a carbon fibre pattern with a black, red and gold colour scheme.
The internal module can run up to a 1,000 Hz refresh rate, and the radio runs EdgeTX firmware, which is preinstalled. EdgeTX is the open source firmware most FPV pilots already know, with a large community and plenty of setup guides.
The screen is a 128x64 monochrome LCD, which is easy to read outdoors and keeps power use low. Power comes from a 7.4 V two-cell LiPo or two 3.7 V 18650 cells, neither of which is supplied, and charging is by USB-C with QC 3.0 fast-charge support. A fan is fitted for the ELRS module. With up to 16 channels available, subject to what your receiver supports, it has plenty of headroom for a drone with extras such as gimbal tilt, camera switches and a buzzer.
Because the transmitter is ELRS-based, it works with ExpressLRS receivers; it is not a multiprotocol radio. If you fly other receiver brands, you will need a separate module or receiver that speaks ELRS.
Pilots moving to ExpressLRS who want a comfortable, well-built radio and would rather not chase modules and adapters. It is also a good step up from an entry-level radio when you notice gimbal wear or want a faster link. Check that you have batteries, because the pack is not included.
