Employing Spektrum's patented MultiLink™ DSMX™ technology, the R1221 uses one internal and three external receivers for path diversity—assuring 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 established the instant voltage returns due to the QuickConnect instant voltage recovery system.
This product is not intended for use by children under 14 years of age without direct adult supervision.
