JRPRO RD921 2.4Ghz 9ch DSM2 Receiver

The JR RD921 9 channel receiver combines Spektrum’s exclusive, patent-pending DSM2 protocol 2.4GHz — 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.
This receiver features a high 2048 resolution when used with the JR X9303 radio system, which is higher than the standard 1024 resolution that is provided by the Spektrum range of DSM2 receivers, such as the AR7000.
The Receiver will fall back to 1024 resolution with transmitters that only support this transmission mode such as the Spektrum DX7.

The RD921 is compatible with all JR DSM2 and Spektrum aircraft transmitter. The RD921 is not compatible with the DX6 first generation DSM park flyer system.
