Frequently Asked Questions

What batteries does the RadioMaster Boxer Max use, and what is its typical operating duration?

The Boxer Max accepts a 7.4V 2S LiPo pack or two standard 3.7V 18650 lithium-ion cells (not included). With a large-capacity 2S 6200mAh LiPo, it can provide up to 20 hours of continuous operation. The integrated QC3.0 fast-charging circuit allows for quick recharging via the USB-C port.

Is the internal ELRS module's RF power adjustable, and does it have a cooling fan?

Yes, the built-in ExpressLRS 2.4GHz module features adjustable RF output power, configurable via the EdgeTX Lua script or the ExpressLRS web interface. The ELRS version of the Boxer Max includes a dedicated internal cooling fan to ensure stable performance during high-power, high-refresh-rate (up to 1000Hz) operation.

Can I use other long-range systems like TBS Crossfire with this transmitter?

Absolutely. The Boxer Max includes a standard JR-style external module bay compatible with systems like TBS Crossfire, FrSky R9, or other JR-formatted modules. The transmitter can supply power to the external module via dedicated slots in the battery cover, allowing seamless integration of additional RF protocols.

How do I update the EdgeTX firmware and the ExpressLRS module firmware?

EdgeTX firmware is updated via the EdgeTX Companion PC software over a USB-C connection. The internal ExpressLRS module firmware can be updated using the ExpressLRS Configurator, either wirelessly via Wi-Fi or via a passthrough flash method through the EdgeTX interface. Both processes are well-documented by the respective open-source communities.
