The R921 combines two internal receivers and one remote receiver for path diversity and ultimate radio installation flexibility. The radio system simultaneously transmits on two frequencies creating dual RF paths. This dual path redundancy, plus the fact the remote receiver(s) are located in different locations exposes each receiver to a different view of the RF environment providing unmatched path diversity.

A second remote receiver can be added to the system to increase the receiver’s view of the RF link. This option might work well in giant scale aerobatic planes or jets where installations become challenging. Remote receiver extensions are available in 6”, 9”, 12”, 24”, and 36” lengths to provide a variety of installation options.

Spektrum’s optional Flight Log (SPM9540) is compatible with the R921. The Flight Log displays the receiver’s real time voltage. It also shows individual internal and remote receivers' RF link data, and overall system RF link performance.

While the optional remote receiver and flight log are not necessary to operate the R921, some large or complex models may benefit from having these items included in the set up. Every model is unique, and JR/Spektrum’s receiver solutions allow you to customize the radio installation to match the unique demands of all your radio system installation needs.
