  • Page 2: Welcome To The World Of Spektrum Dsm2 Full Range Technology

    Welcome to the World of Spektrum DSM2 Full Range Technology Spektrum’s DX7 is the first-ever full range 2.4Ghz Spread Spectrum Radio system for R/C aircraft. With Spektrum’s DSM2 ™ technology, now even large gas- and glow-powered aircraft can take advantage of Spektrum technology.

  • Page 3: Dsm2 Dualink Technology

    AR6000 Parkflyer Compatible You’ll be glad to know that the DX7 is compatible with the AR6000 mini park flyer receiver, however, when using the AR6000 receiver, aircraft type is limited to parkflyers and mini and micro helicopters only. Simply bind the DX7 transmitter to the AR6000 and you are ready to fly.

  • Page 4: Model Match

    The DX7 features Model Match technology that prevents the operation of a model if the wrong model memory is selected. During binding, the receiver actually learns and remembers the specific model memory (1 of 20) that the transmitter is currently programmed to.

    The pilot lamps should always be ON during the charging operation. If they’re not, check to make sure that both the transmitter and receiver are switched OFF. Do not use this charger for equipment other than Spektrum. The charging plug polarity may not be the same and equipment damage can result. During the charging operation, the charger’s temperature is slightly elevated.

    Advanced Digital Trims The DX7 employs digital trim levers on aileron, elevator, throttle, and rudder. (Hover pitch and hover throttle for helicopters). The ADT (Advanced Digital Trim) feature is designed to automatically store the selected trim values for each model. When a different model is selected, the previously stored trim positions for that model are automatically recalled.

    6” extension. By locating these receivers in slightly different locations in the aircraft, each receiver is exposed to its own RF environment, greatly improving path diversity (the ability for the receiver to see the signal in all conditions). SPEKTRUM DX7 • INTRODUCTION...

  • Page 15: Receiver Installation

    Receiver Installation Install the main receiver using the same method you would use to install a conventional receiver in your aircraft. Typically, wrap the main receiver in protective foam and fasten it in place using rubber bands or Velcro straps. Alternately, in electric models or helicopters, it’s acceptable to use thick double-sided foam tape to fasten the main receiver in place.
  • Page 16 Receiver Installation (continued) In helicopters, there is generally enough room on the servo tray to achieve the necessary separation. If necessary a mount can be fashioned using clear plastic to mount the external receiver.

  • Page 17: Servo Installation

    Before each flying session, and especially with a new model, it is important to perform a range check. The DX7 incorporates a range testing system which, when the bind button on the back of the transmitter is pressed and held, reduces the output power, allowing a range check.

  • Page 18: Binding

    Binding The AR7000 receiver must be bound to the transmitter before it will operate. Binding is the process of teaching the receiver the specific code of the transmitter so it will connect to that specific transmitter. Once bound, the receiver will only connect to the transmitter when the previously bound model memory is selected. If another model memory is selected, the receiver will not connect.
  • Page 19 6. After you’ve programmed your model, it’s important to rebind the system so the true low throttle and neutral control surface positions are programmed. Note: The AR7000 features DSM2 ™ technology and is only compatible with DSM2 transmitters. The AR7000 will not operate with the DX6 or Spektrum ® surface systems. SPEKTRUM DX7 • INTRODUCTION...
