JR R921 Receiver
G-10
The R921 receiver combines two internal with one or
two (optional) remote receivers, offering superior path
diversity. The radio system simultaneously transmits
on two frequencies, creating up to four RF paths on two
different 2.4GHz channels. This multi path redundancy,
plus the fact that each of the up to 4 receivers are located
in different locations throughout the aircraft exposes each
to a different RF environment creating a superior RF
link in all conditions. The JR R921 allows the use
of an optional Flight Log Data Recorder (SPM5940) to
be used. The flight log plugs into the data port and
provides quality of RF link data of the previous flight
allowing the confirmation of the operational performance
of the systems.

Note
: The X9303 2.4 is compatible with all current Spektrum DSM aircraft receivers including:
AR6000 6-channel parkflyer receiver
AR6100 6-channel 3.5-gram parkflyer receiver
AR6200 6-channel full-range receiver
AR7000 7-channel full-range receiver
AR9000 9-channel full-range receiver
Important
: When using the X9303 2.4 with parkflyer receivers (the AR6000 and AR6100), it’s imperative that these
receivers only be flown in parkflyer-type aircraft (small electric airplanes or mini and micro helicopters). Flying
receivers designed for parkflyers in larger aircraft could cause loss of control.
