This is the JR R1221X 12 Channel DSMX Receiver. Employing Spektrum's patented MultiLink™ DSMX™ technology, the R1221X uses one internal and three external receivers for unmatched signal path diversity. This assures your receiver always "sees" a strong signal and is unaffected by multi-path issues. What's more, DSMX air receivers employ DuaLink® two-frequency technology, ensuring your aircraft always operates with an ultra-secure, robust RF link.

Dual battery ports are provided with the R1221 for power redundancy. The receiver will handle well over 35 amps of continuous current, the limiting factor being the connectors. In the unlikely event your voltage should ever drop below 3.5 volts, control is restored as soon as voltage returns.
