JR RD721 Key Overview
The JR RD721 receiver combines Spektrum's exclusive, patent- pending DSM2 protocol plus the brand's DuaLink feature-and the result has been revolutionary. The radio system simultaneously transmits on two frequencies, creating dual RF paths. This dual path redundancy, plus the fact that each of the two receivers is located in a slightly different location exposes each to a different RF environment and creates a superior path diversity RF link in all conditions.
