Overview

With the DX7 you'll be able to fly anything from micro helis to big gas-powered giant-scale planes without regard to frequencies and free from fear of interference.  Calling this kind of thing "revolutionary" just doesn't cut it.  It is nothing less thean a quantum leap in RC technology that will change how you fly forever.  Never again will the availablity of a frequency pin dictate when you can take off.  Never again will you have to ask, "What channel are you on?"  Never again will your flying experience be interrupted by model-generated RF noise, interference from commercial broadcast towers, or anyone on another RC system.

The DX7 transmitter only includes:

1 Transmitter
1 1500mAh Transmitter battery pack
1 Charger
1 Manual

What ESCs and servos can I use with Spektrum Receivers?

Spektrum receivers are compatible with most popular speed controls and servos on the market.

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 2.4GHz 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.

What is DSM2?

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.

What is DSMX?

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.

What is Frequency Agility?

These systems usually transmit a narrow band signal and rapidly jump through a fixed set of frequencies, spending a few milliseconds on each frequency.

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.

Are DSMX and DSM2 equipment compatible with each other

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.

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 ModelMatch?

A safety feature that prevents a pilot from flying a model when the model selected in the radio is not correct.

What is Servo Sync?

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.

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?

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.

Where can I find Spektrum Apps?

You can download Spektrum Apps from the Google Play Store at https://play.google.com/store/apps/developer?id=Horizon+Hobby,+Inc. or from the iTunes store at https://itunes.apple.com/us/developer/horizon-hobby-inc/id415542050

Can I change/shorten/lengthen the antenna on my Spektrum Receiver?

The length of the antenna is on a Spektrum receiver is set and tuned to optimize the range and performance of the receiver. We do not recommend altering the length of the antenna on any Spektrum Receiver.
