Using specifically developed JR® DMSS* technology, the all-new XG8 radio system provides a reliable 2.4GHz radio link with the ability to control popular model types within the airplane, helicopter or glider categories. In addition, the XG8 offers an Intelligent Output System for enhanced control accuracy and advanced telemetry functions to display critical flight data when you need it most.
The XG8 is the first JR transmitter to come with a Li-Fe battery, which has greatly reduced it weight. Inside the transmitter is an integrated charging circuit that automatically shuts down when the battery reaches full charge. No more worries of overcharging. Programming is easy thanks to the 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.
Dual Modulation Spectrum System (DMSS) 2.4GHz protocol offers a secure radio link that combines DSSS and FHSS capabilities into a wideband transmission system and includes high-speed response and high resistance against RF noise. One benefit of DMSS* is the JR Intelligent Output System (IOS), which automatically selects control signals that need to be transmitted at exactly the same time and delivers the data as one complete signal frame. IOS ensures there is no time delay when commanding servos used for critical functions, such as a CCPM swashplate on a helicopter, or when operating a wing control surface with multiple servos.
Another feature of DMSS is its bi-directional communication that supplies telemetry information. Receiver voltage telemetry is built in as standard in every DMSS receiver, and 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.
DSM or Digital Spectrum Modulation is Spektrum's proprietary method of implementing 2.4GHz spread spectrum technology for the R/C industry. DSM divides the 2.4GHz band into 80 individual channels (frequencies) and incorporates direct sequence spread spectrum with an embedded GUID (Globally Unique Identifier) code. DSM has been painstakingly optimized by our engineers for RC surface and aircraft use, offering the most robust RF link in the industry.
DSM2 is the 2nd generation of Spektrum DSM technology and remains a premier 2.4GHz choice even today. Using the same superior wideband DSSS foundation that all Spektrum technology is based on, DSM2 consistently provides faster response and more precision than most non-DSM 2.4GHz protocols.
DSMX is a natural evolution of DSM2 technology that is the result of several years of development, optimized for pilots and combining Wideband DSSS and Frequency Agility. It builds on what has come before and takes DSM to the next level of robustness, reliability and efficiency without leaving current DSM2 users behind. DSMX represents the world's first wideband, frequency-agile 2.4GHz signal protocol and the most advanced spread spectrum RC technology to date.
The foundation DSMX is built on is the same foundation as DSM2™ - the superior on-channel interference resistance and coding gain of wideband DSSS. Compared to the wideband signal of a DSM2 or DSMX™ system, the narrow-band signal of other 2.4 transmitters is more likely to suffer crucial data loss in the event of on-channel interference. Think of wideband 2.4 as a river and narrow-band 2.4 as a stream. It takes much more interference to stop a river than it does to stop a stream.
The big reason wideband is so robust is coding gain. Essentially what this means is that the unique coding in a DSM2 or DSMX wideband signal allows it to be heard well above the noise of surrounding 2.4GHz signals without requiring any more power. In fact, a Spektrum wideband signal can achieve as much as 3X the range of its narrow-band competition using the same amount of power.
For the most part, yes. DSM2 transmitters are forward compatible with DSMX receivers and DSMX transmitters are backward compatible with DSM2 receivers. And because DSM2 and DSMX share the same wideband DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they're using DSM2 equipment, DSMX equipment or a combination of both. The only exception is the DXe which is DSMX-only and not compatible with DSM2 receivers.
Yes, but DSM2 users who rarely, if ever, fly in big events or other "noisy" 2.4GHz environments may find the DSM2 equipment they have now is all they will ever need. The difference DSMX makes is only apparent when hundreds of 2.4GHz systems are in use at once. To see if your transmitter is eligible for the DSMX add-on, please visit horizonhobby.com, click on the “radios” tab, and select “DSMX addons” for more details.
A resequencing of the data a Spektrum transmitter transmits based on the type of mixing you select. This feature helps to sync control services that are connected (such as a swash plate on a helicopter) and is used in radios that have many channels.
The Spektrum™ X-Plus™ 8 module lets you add 8 fully proportional channels to specially equipped Spektrum transmitters and receivers with 10 or more proportional channels. Just plug it into the X-Plus port of a compatible receiver. It is ideal for scale modelers who like to push realism to the extreme with working accessories and lights in addition to the regular control functions. The DX10t and DX18 offer X-Plus.
You should have no problem maintaining control as long as you maintain direct line-of-sight with your model. If you try to fly behind a group of trees or otherwise obstruct your direct line-of-sight, you could be susceptible to losing your control link.
