The Spektrum DX7 does away with all that 72Mhz/75Mhz mess and moves on to a whole NEW band- 2.4Ghz! This Digital Spread Spctrum radio system is a significant upgrade from the DX6, not just 1 additional channel, but a whole range of NEW programming and mixing options!

Glitching and range impairment from motor, servo, ESC and mechanical RF “noise” will be a thing of the past. And no form of channel selection will be necessary on your part. Your DX7 selects the channel for you. When you fire up your DX7, it searches for, selects and locks onto clear channels. (There are 80 channels in the 2.4GHz band.) And because international regulation of the band is very strict, your radio will neither sustain interference from – nor cause interference to – any other 2.4GHz device worldwide. And that applies, of course, to its simultaneous operation near other 2.4GHz RC radios as well. DX7 frequencies are so much higher than those of conventional RC channels that you radio won’t even recognize the existence of 27,50, 72 or 75MHz RC signals. Nor will conventional RC receivers “hear” your DX7 transmissions.

In short, 2.4GHz DSM RC is a win-win deal for everyone!

A whole new type of receiver.
The AR7000 dual receiver that comes with the DX7 is key to the system’s incredibly robust RF link. Comprised of a compact main receiver that is linked to an even smaller satellite receiver by a 6” lead, the AR7000 acts as a pair of extremely sharp RF “eyes” that each take in a slightly different view of the signal environment. Information from both receivers is then processed by patent-pending Spektrum software that takes information from each receiver and combines it to form the most vivid “picture” of an RF signal than has ever been possible before. What’s more, there are no long antennas to accommodate. The AR7000’s short 3” antennas don’t require any external exposure, so installation is an absolute breeze.

AR6000 and BR6000 compatible.
DX6 owners will be pleased to know that both the AR6000 and BR6000 receivers work perfectly with this DX7 radio. In fact, these receivers will actually benefit from the DX7’s signal speed advantages, as well as ModelMatch and ServoSync functionality.
