This is the Spektrum AR9000 DSM2 9-Channel DuaLink Aircraft Reciever.  This receiver features an external and internal receiver for even greater reliability.  An additional remote receiver can be added for great security, which is especially nice if flying a scale aircraft, aerobatic, or jet aircraft.  This receiver works only with DSM2 capable radio systems and module systems.

Features

• 9 Channels
• External and Internal Receiver
• DuaLink
• ModelMatch prevents flying a model using the wrong model memory (feature does not work with module systems)
• ServoSync (feature does not work with module systems)
• SmartSafe fail-safe system

Overview

The AR9000 combines two internal receivers and one remote receiver for path diversity and ultimate radio installation flexibility. The radio system simultaneously transmits on two frequencies creating dual RF paths. This dual path redundancy, plus the fact the remote receiver(s) are located in different locations exposes each receiver to a different view of the RF environment providing unmatched path diversity.

A second remote receiver (SPM9545) can be added to the system to increase the receiver’s view of the RF link. This option might work well in giant scale aerobatic planes or jets where installations become challenging. Remote receiver extensions are available in 6”, 9”, 12”, 24”, and 36” lengths to provide a variety of installation options.

Spektrum’s optional Flight Log (SPM9540) is compatible with the AR9000. The Flight Log displays the receiver’s real time voltage. It also shows individual internal and remote receivers' RF link data, and overall system RF link performance.

While the optional remote receiver and flight log are not necessary to operate the AR9000, some large or complex models may benefit from having these items included in the set up. Every model is unique, and Spektrum’s receiver solutions allow you to customize the radio installation to match the unique demands of all your radio system installation needs.

Tech Notes
Note:
The AR9000 features DSM2™ technology and is only compatible with DSM2 transmitters. The AR9000 will not operate with the DX6 or Spektrum® surface systems. 

The AR9000 requires that at least one remote receiver be used (one is included), but can use a second remote receiver if desired.
