Daily briefing
RadioMaster's ER12 and ER3 Pro dual-band ExpressLRS PWM receivers are listed for orders to begin shipping at the end of September. Both use 2.4 GHz plus sub-GHz Gemini-X links and require ExpressLRS 4.1.0 or later. RadioMaster states that it cannot obtain FCC certification for these products because it considers them foreign-produced UAS components under current U.S. rules, so it is not shipping or selling them in the United States.
The regulatory note directly affects availability of new RC radio hardware even though the receivers target conventional fixed-wing and other PWM-controlled models as well as drone-related use.
U.S. builders should not assume overseas availability means lawful domestic sale or use. Elsewhere, verify the correct FCC/LBT regional version and local spectrum rules before ordering.
