RadioMaster Boxer 2.4GHz Radio Transmitter (M2)

The RadioMaster Boxer is a compact ELRS 2.4GHz transmitter built around full-size Hall effect gimbals and an STM32F407VGT6 processor, running EdgeTX firmware out of the box. Its ergonomic handle and standardised button layout suit freestyle, racing and general FPV flying for pilots who want a smaller radio without giving up a proper dual-gimbal layout.
