JR - JRPR921X - R921X 9-Channel DSMX Receiver

The JR R921 receiver combines Spektrums exclusive, patent-pending DSMX protocolplus the brands patented DuaLink® technologyand 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.

This product is not intended for use by children under 14 years of age without direct adult supervision.
