DSM2—Security and Speed:
Unlike most first-of-its-kind innovations, DSM2™ is not an unproven concept. It is based on the same Spektrum 2.4GHz DSM (Digital Spectrum Modulation) that RC car racers, as well as micro electric and park flyer modelers, have been enjoying for at least two years. Like DSM, DSM2 provides an impenetrable radio link that’s immune to every known type of RC interference. Because it operates at 1024-bit resolution, it provides the kind of locked-in response that will have pilots feeling more connected to their models than ever before.

AR7000—Spectacular Signal Clarity:
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.

ServoSync and ModelMatch—Extra Safety and Precision:
DSM2 and the AR7000 aren’t the DX7’s only marvels.Spektrum engineers have come up with two more patent-pending innovations that you’ll wonder how you ever lived without— ModelMatch™ and ServoSync™. ServoSync is an ingenious new feature that actually resequences the bits of data the DX7 transmits based on the type of mixing you select. So, if you have a dual elevator on your big Extra or a 3-servo CCPM setup on your heli, ServoSync will see to it that those servos working together receive their impulses together. The result is more synchronized servo movement that translates into an undeniable, locked-in feel when you fly. ModelMatch puts an end to the “wrong model” syndrome. Almost everyone who flies RC has at one time or another crashed because he neglected to verify the model name on the transmitter display in his preflight check. A unique code is embedded in the DX7’s signal so that, if the wrong model’s name is on the screen, the model’s controls simply won’t respond.
