What is DSMX?

DSMX builds upon the incredible DSM2 technology you have come to know and trust. After years of development and in the field use, DSMX is an evolution of DSM2 2.4 GHz technology, destined to deliver the most robust, reliable, and efficient level of RF link possible in the modeling world today.

DSMX is for those modelers who enjoy attending mega events where large numbers of 2.4 systems are on at once. Another great part about all of this is the forward/backward compatibility of DSMX to DSM2 is such that no current technology becomes orphaned with the release of todays or future DSM transmitter products.

It is a new, frequency agile evolution of Spektrum 2.4GHz technology that matches the consistently superior speed and data capacity of DSM2 with the most advanced frequency shifting algorithm to date.


Should I purchase the $75 DSMX add-on?

Before investing in the DSMX transmitter add-on, there are several important facts about DSMX you need to know:

  • To realize the full benefits of DSMX technology you must have both a DSMX Transmitter and a DSMX Receiver
  • DSM2 transmitters are compatible with DSMX receivers. Likewise, should you add-on to a DSMX transmitter, the DSM2 receivers you have now will be compatible with it.
  • Because DSM2 and DSMX share the same wide-band DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether theyre using DSM2 equipment, DSMX equipment or a combination of both.
  • The difference a DSMX system makes is only apparent when hundreds of 2.4GHz systems are in use at once.* DSM2 users who rarely, if ever, fly in big events or other exceptionally "noisy" 2.4GHz environments may find the DSM2 equipment they have now is all they will ever need.

    *A DSMX system refers to a DSMX transmitter in use with a DSMX receiver.

Just How Good is DSMX?

In multiple tests, 100 DSMX systems were operated simultaneously for extended periods of time. During these tests not a single case of RF link loss, latency increase or control degradation was experienced or recorded.

See the 100 transmitter test for yourself. Watch the DSMX video above.


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.


Can I send in my DSM or DSM2 Receivers for the $75 DSMX add-on?

Horizon Hobby can not add DSMX Technology to any DSM or DSM2 Receivers.

Transitioning to DSMX will result in loss of compatibility with DSM technology. (Spektrum AR6000, Spektrum BR6000)

However, because DSM2 and DSMX share the same wide-band 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.*

*DSM2 and DSMX Remote receivers are not interchangeable.


Is the $75 DSMX add-on available for my JR 72 MHz transmitter?

The DSMX add-on is only compatible with 2.4 GHz transmitters.


Is the $75 DSMX add-on available for my JR 12X MV transmitter?

Yes, the DSMX add-on is compatible with your transmitter.

Important Note: You are only required to send in your 2.4Ghz module to receive the DSMX add-on. You do not have to include your transmitter.
