Detailed Information

Spektrum™ telemetry technology makes it possible for you to get real-time information on your model's battery voltage, motor rpm, motor temperature and more. Many Spektrum transmitters feature built-in telemetry data receivers that let you view this information on their LCD screens. You also have the option of monitoring telemetry using the Spektrum STi™ app for the Apple® iPad®, iPhone® or iPod touch® mobile digital device.

The Spektrum brand is releasing new telemetry sensors and accessories all the time. To give you a feel for what a difference Spektrum telemetry can make, here are some of the most commonly used telemetry features most Spektrum users take advantage of:

The Spektrum STi™ Telemetry Interface for iPhone®, iPad® and iPod touch® mobile digital devices
The STi unit lets you transmit vital info from your model’s onboard Spektrum telemetry module directly to your iPhone®, iPad® or iPod touch® mobile digital device.* It can also be programmed to alert you when any telemetry value you’re monitoring exceeds limits you define. It’s a great way to keep tabs on your model if you’re flying with a DSM2®/DSMX® Spektrum or JR®/DSM® transmitter that doesn’t have built-in telemetry. Even with a telemetry-capable transmitter, you can use it to let someone else watch telemetry, so you can focus completely on flying.

*Requires the free STi app. Works with iPad®, iPad® 2, iPod touch® (4th gen), iPhone® 4S, iPhone® 4, iPhone® 3GS, iPhone® 3G.

Battery Voltage
Never again will you have to wonder whether or not you have enough voltage to keep flying. Being able to monitor voltage will also help you detect a worn out battery pack before it prematurely ends your flight. The telemetry module is plugged into the receiver and will automatically relay receiver voltage. A separate sensor for tracking flight pack battery voltage in electric aircraft is also available.

Temperature
Is the engine running too lean? Is there enough air flow reaching an electric motor? Is my battery getting too hot? Get real-time answers and take action well before damage occurs.

Signal Quality
Spektrum telemetry modules keep tabs on the quality of the signal coming to the receiver and send this information back to the transmitter where it is represented on the LCD screen.

RPM
Pilots can use the rpm telemetry data to check the effectiveness of new mixture settings, new battery packs or perhaps a new propeller/motor combination.


You can now experience the advantage of real-time telemetry via several compatible transmitters.

FAQs

Is Spektrum allowed at AMA flying events?

The AMA (Academy of Model Aeronautics) has certified its use at all AMA fields and events when used as per the manufacturer's instructions. In fact, most event directors welcome Spektrum, as it eliminates the issues of frequency management.

What is DSM?

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 2.4 GHz band into 80 individual channels (frequencies) and incorporates direct sequence spread spectrum with an imbedded 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.

What is the difference between DSM and DSM2

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 2.4 GHz band into 80 individual channels (frequencies) and incorporates direct sequence spread spectrum with an imbedded 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.

What is DSMX?

A Natural Evolution

Spektrum launched the 2.4GHz RC revolution. Since then millions of hobbyists the world over have come to embrace 2.4GHz technology as the way to race and fly. Spektrum leads the way yet again with DSMX™; the world's first wideband, frequency-agile 2.4GHz signal protocol and the most advanced spread spectrum RC technology to date.

 

DSMX is a natural evolution of DSM2™ technology that is the result of several years of development. 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.

What is Frequency Agility?

What DSMX™ adds to the tried and true wideband technology of DSM2™ is the extra interference protection and faster reconnection times of frequency agility. But DSMX isn't just another frequency hopping system. It’s wideband agile.

DSMX frequency shifts are coordinated using the most advanced FHSS algorithm ever seen in an RC application. Unlike other FHSS transmitters that all hop in the same fixed patterns, every DSMX transmitter has its own unique frequency shift pattern calculated using its GUID (Globally Unique Identifier). And each pattern uses just 23 channels in the 2.4GHz spectrum.

By adding the agility of unique frequency shifts to the superior interference resistance of a wideband signal, and limiting those shifts to a smaller portion of the 2.4 band, DSMX transmitters provide on-channel interference protection that is simply second to none. The result is quicker reconnection times and superb response in the noisiest 2.4GHz environment.

What is Wideband DSSS?

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.

Is DSM2™ and DSMX equipment compatible?

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.

Are DSM2 transmitters eligible for a DSMX add-on?

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.

What is Spektrum AirWare™ Software?

Spektrum AirWare™ software was developed exclusively by Spektrum from the ground up. This software includes all the programming functions an expert pilot could want, but you don't have to be an expert to use them. It also brings several unique benefits to Spektrum programmable transmitters that simply aren't available on other systems.

What is the Spektrum™ Data Interface?

The Spektrum™ Data Interface (SDI) is designed for use with standard SD memory cards and adds a whole new level of flexibility and ease-of-use. With the SDI, you will be able to:

Share setups with others who use the same radio as yours or transfer setups from your SD card to your PC and attach them to an e-mail. This makes it easy to gain from the experience of others or help others succeed. With the SDI, memory for thousands of models could be stored on the SD card or transferred to a PC hard drive for backup. And you can stay up to date with SDI, you won't have to send your Spektrum radio into a service center to get the latest Spektrum AirWare™ enhancements. You can download them onto your SD card and upload them to the transmitter yourself.

Does DSMX have ModelMatch™ and ServoSync™?

Yes. DSMX will provide users with these and the many other exclusive Spektrum advantages they already enjoy with DSM2.

What is X-Plus™?

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.

How much range can I expect out of my radio system?

Spektrum ParkFlyer receivers are designed for small models up to 2 pounds. Spektrum full range receivers are designed to handle any normal RC conditions. You should have no problem maintaining control as long as you maintain direct line of site with your model. If you try to fly behind a group of trees or otherwise obstruct your direct line of site, you could be susceptible to losing your control link.
