JR-PROPO-XG8 8-channel DMSS Transmitter with RG831B Rx, Black
Overview
The XG8 DMSS Telemetry Radio System from JR is an outstanding addition to the market and JR's line of superb-quality radios. The first Radio to incorporate JR's own DMSS Technology - Dual Modulation Spectrum System - 100% JR, it leads the way for a new era in Radios.
The XG8 is the first JR transmitter to come with a 2S Li-Fe battery, being fitted with a 1400 mAh pack. This has greatly reduced the weight of the transmitter, which weighs in at only 770 grams. It also ensures perfect balance. The transmitter has an integrated charging circuit so just plug in the AC adapter supplied and the charging unit will shut down automatically once it detects that the battery is fully charged. No more worries overcharging! The XG8 offers Aeroplane, Helicopter and Glider modes, a 30 model internal memory, stick modes 1 to 4 and an SD card slot for model data sharing, expanded storage and software updates (SD card not supplied).
Programming is easy thanks to JR's well-proven, intuitive user interface with data entered using the familiar scroll bar and four push-button entry keys. The programming information is clearly displayed on the large, graphical back lit screen. XG8 uses the new JR DMSS 2.4 technology which, besides offering a secure, robust radio link to control your models, also offers advanced telemetry functions and JR's new Intelligent Output System. Receiver voltage telemetry is built in as standard and other forthcoming add-on sensors will give you real time feedback of information from your model such as the RPM of an aircraft propeller or helicopter rotor blades, temperature and variometer/altimeter readings.
JR's Intelligent Output System automatically selects control signals that need to be transmitted at exactly the same time and transmits the data for these channels as one complete signal frame. This ensures that there is no time delay when commanding servos used for critical functions such as a CCPM swash plate on a helicopter or when operating a four servo aileron wing. Other features include side-lever controls on either side of the transmitter, a Touch Select System for switch selection, dual trim options, a user selected menu for frequently used functions, failsafe on all eight channels, user assigned switch function, programmable throttle cut and two independent programmable timers.
What is JR DMSS?
Dual Modulation Spectrum System is JR's own 2.4GHz protocol. Although a late entry to the 2.4GHz market, DMSS can be considered as the truly 'state of the art' method of providing radio control for model use. And since JR have not rushed their own 2.4 protocol into production, they have been able to incorporate the very latest techniques for 'Wideband Data Transmission' into the next generation of JR radio control sets.
DMSS combines the best features of Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS) protocols. FHSS is great for avoiding interference and DSSS offers high response. JR DMSS combines both these attributes, having both frequency hopping and high response.
The JR DMSS system uses a greater than 3Mhz wide signal as compared to the majority of others which utilise a much narrower [1Mhz or less] signal.
