JR XG7 7-Channel 2.4GHz DMSS Transmitter w/RG831B Receiver With 3 x JR539 (Mode 2)

This radio heralds the introduction of JR’s very own DMSS 2.4GHz technology. DMSS stands for Dual Modulation Spread Spectrum, which basically means that it operates using a wider spread signal than a traditional ‘frequency hopping spread spectrum’ system (FHSS). By hopping using a widespread signal, DMSS is much more resistant to interference than a conventional frequency hopper.

This stylish transmitter is based on JR’s well-proven X2720 35MHz radio, but with the addition of a scroll bar interface and telemetry. It offers aircraft and helicopter set-ups. A new feature in helicopter mode is the ability to resequence the transmission of the cyclic signals on channels 2, 3 and 6, without waiting for channels 4 and 5 to be processed. This speeds up cyclic response when the XG7 is used for fast 3D flying.

As standard the XG7’s telemetry system monitors receiver battery voltage. When the receiver battery reaches a pre-set level the transmitter will sound a warning. The receiver battery voltage is also shown on the transmitter’s large, clear display. Additional telemetry sensors for RPM and temperature measurement will be available.

The XG7 is supplied with one of JR’s new eight channel RG831B DMSS receivers, fitted with a remote antenna. A 1500 mAh Ni-MH transmitter battery, genuine JR charger and a heavy-duty switch harness will also be included.
