RadioMaster says its ER12 receiver cannot currently be sold in the United States
RadioMaster's ER12 dual-band Gemini/Gemini-X receiver page lists the product at $59.99 but currently shows it sold out. More importantly, the company states that it cannot obtain FCC certification for the product under current U.S. rules because it is classified as a foreign-produced UAS component, and says it cannot ship or sell the receiver in the United States at this time.

Component-level regulatory constraints can affect RC builders even when a product is not an aircraft. Receivers, radios and other modules can become supply-chain bottlenecks independently of airframe availability.
Treat this as RadioMaster's current statement about its U.S. availability, not a general legal interpretation for every receiver. Builders should check the exact regional SKU and current shipping status before planning a new aircraft around it.
