Overview

With the DX7 you’ll be able to fly anything from micro electric helis, to big gas-powered IMAC 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 than a quantum leap in RC technology that will change how you fly forever. Never again will the availability 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 big difference with DSM2 is that it not only flies any size model with absolute precision and complete freedom from interference, but it also processes its signal faster than any high-end 72MHz PCM system.

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 parkflyer 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-inch 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-inch 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 wrong model syndrome. Almost everyone who flies RC has at one time or another crashed because of neglecting to verify the model name on the transmitter display during 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.

AR6000-Compatible:
DX6 owners and anyone else who flies small electric models will be pleased to know that the AR6000 receiver works perfectly with the DX7, too. In fact, the AR6000 will actually benefit from the DX7’s signal speed advantages, as well as ModelMatch and ServoSync. So whatever the aircraft, be it a .60-size heli or a 15-ounce foamie, it can fly with the DX7.

Always purchase products from a Horizon Hobby, Inc. authorized dealer to ensure authentic high-quality Spektrum product. Horizon Hobby, Inc. disclaims all support and warranty with regards, but not limited to, compatibility and performance of counterfeit products or products claiming compatibility with DSM2 or Spektrum.

Attention: Horizon Hobby has confirmed that all Spektrum Products being sold by KoKo Technology are counterfeit. We consider it a danger to use these products, waive all liability and will not support any warranty or service in regards to them.

The AR7000 Dual Receiver is capable of providing outstanding signal reception beyond visual range, so you can rest assured you have locked-in, precise control no matter how fast you fly.
Includes 4 powerful DS821 digital servos with high-tech resin gears.
The DX7 incorporates a three-position flap system that allows the flap and elevator positions to be preset in all three switch positions. An auto function automatically retracts the flaps when the throttle is raised above a preset point.
Punch in dual rate and exponential values in the same screen for aileron, elevator and rudder and see the result clearly and graphically depicted on the displayed curve.
Keep real-time tabs on each channel’s control position, direction of movement and mixing relationship with this all-in-one servo monitor that can help you visualize mixes before flying.
The DX7 offers switch assignment that lets you conveniently combine dual rates on one of many switches or program them to be activated separately.
Four flight modes (normal, stunt 1, stunt 2 and hold) are available, each with its own five-point throttle and pitch curve. Graphical depiction of the curves makes adjustments clear and easy to understand.
The DX7 supports mechanical mix helis as well as 3 types of CCPM mixing, including 2 servo 90°, 3 servo90° and the most common 3 servo 120°. Swashplate aileron, elevator and pitch values are independently adjustable, making precise setup easy.
The gyro function allows two gyro gain presets that can be automatically accessed via flight modes or with the rudder dual rate switch.
