Spektrum receiver AR637T+ AS3X+/SAFE with telemetry

Package contents

The package includes the Spektrum AR637T+ RC receiver, a cable for measuring external voltage, a multilingual manual in English, German, French and Italian and instructions in Czech.

Characteristics

The Spektrum AR637T+ RC receiver with integrated AS3X+® and SAFE® stabilization and telemetry, has the new AS3X+ stabilization algorithm and greater sensor accuracy and data rate, therefore there is no delay in control or response of electronic stabilization. The AR637T+ features full range telemetry and an integrated barometer that provides altitude and varia data.

SAFE and AS3X stabilization

The AS3X+ and SAFE are programmed and set up directly from your Spektrum transmitter* using Forward Programming in 3 steps. To use SAFE and AS3X+ technology with the AR637T receiver, the receiver must be paired with a compatible Spektrum transmitter. With Forward Programming, no apps or cables are needed to program or make changes at the airport.

The AR637T+ features full range telemetry and an integrated barometer that provides altitude and vario telemetry data. The XBUS, RPM, voltage and temperature connectors can be used to add additional telemetry sensors that are available separately. It also features an SRXL2 connector for an external SRXL2 receiver (SPM9747), which is available separately, to add additional RF path redundancy. The SRXL2/Bind/Program/Batt servo connector is available for connecting Smart devices, programming and updating the receiver, connecting to a traditional connecting plug or connecting a battery.

New features of Smart Transmitter Model Files

The AR637T+ also features a button for easy pairing, SmartSafe™ and Hold Last technology, as well as preset Failsafe types that are set via Forward Programming. In addition, Smart Transmitter Model Files allow BNF models to be stored in the receiver to automatically set the model during pairing.

Compatibility with the Spektrum Smart system

The Spetrum AR637T+ is ready for use with Avian SMART controllers . Receiver output #1 (THRO - throttle) automatically detects if a SMART controller is connected.

If a SMART controller is connected, the receiver automatically reads all telemetry data from the controller (or from the connected SMART battery). Otherwise, a standard servo signal will appear at the output. This ensures compatibility with conventional regulators or servos.

Full range telemetry

The telemetry transmit power is 100 mW EIRP, which guarantees full telemetry range . The receiver is equipped with an XBUS port for connecting other telemetry sensors and a connector for measuring external voltage. The receiver has an integrated barometric sensor , so the receiver measures altitude as well as vario.

Easy pairing with the push of a button

You don't need a pairing plug anymore! To pair, just press the button with the Spektrum logo on the top of the receiver. Pairing can be activated both when the power is turned on and by pressing the button after the power is turned on. This is advantageous where pressing the button and connecting the power at the same time is very difficult to manage "at once".

The possibility of pairing the receiver using the pairing connector connected to the Bind/Prog/SRXL output was still maintained.

NEW GENERATION AS3X® TECHNOLOGY

The brand new AS3X+ 3-axis stabilization features a significantly improved stabilization algorithm that has been thoroughly tested by experts. The system is even easier to tune and can be easily optimized for any type of aircraft. Most aircraft can be prepared for flight in less than five minutes! Main improvements: Stop Lock and Release Rate parameters, Heading Hold, gyro filtering, Canard and Thrust Vectoring support.

SMART TRANSMITTER MODEL FILES SUPPORT

Smart Transmitter Model Files is a new feature in the AR637T+ receiver that makes transmitter programming much easier. It consists of a set of transmitter configuration parameters that are stored in a receiver model file. When paired with a receiver containing one of these model files, the user will be prompted to download said model file and overwrite the currently selected transmitter model with the model stored in the receiver. This will give the user an easy and simple way to get the transmitter model settings for their BNF model without having to set it up themselves or search and download the corresponding model online.
Note: iX20, iX14 and NX transmitters are currently supported with the latest firmware updates.

RECEIVER PROGRAMMING

You can program and set up the AR637T wirelessly directly from any compatible Spektrum™ G2, Nx or iX transmitter via the Forward Programming menu.
Note: The receiver can only be updated to the latest firmware version in the Spektrum Programmer application, but the programming of the receiver itself can only be done in the Spektrum transmitter, compatible with the new generation DX G2/G3, NX iX. To display the Forward Programming menu in the transmitter, it is necessary to have the transmitter paired with the AR637T+ receiver, after pairing, Forward Programming will appear in the Function menu and you can start programming the receiver.

SAFE® TECHNOLOGY

SAFE® (Sensor Assisted Flight Envelope) flight modes help pilots avoid losing control of the model. SAFE uses AS3X to ensure smooth and stable level flight, plus the SAFE feature will limit roll and pitch angles and prevent the model aircraft from entering extreme flight positions.

SAFE® PANIC

Sometimes called rescue mode, Panic is a SAFE stabilization mode that returns the aircraft to level flight from any position. It is usually assigned to a transmitter button or switch.

SMART TELEMETRY

To take full advantage of Smart™ technology, use the AR637T+ receiver with SMART controller and Spektrum DSMX® transmitter with telemetry. Telemetry data such as current, voltage, temperature and rpm are sent directly to your transmitter in real time.

INTEGRATED BAROMETER

The Spektrum™ AR637T+ receiver features an integrated barometer (built-in pressure sensor) that provides telemetry of altitude and vario data, without the need to purchase additional sensors

*Note: DX7S and DX8 Gen 1 Spektrum transmitters do not display altitude or variometer telemetry with the AR637T+ receiver.

These transmitters do not support devices with Forward Programming: DX6i, DX6G2 (EU version), DX7, DX7S, DX7SE, DX7G2 (EU version), DX8, non-computer transmitters. Check out www.spektrumrc.com for the latest updates on your receivers and transmitters.

We recommend to buy

An optional SRXL2 receiver (order number SPM9747) can be connected to the receiver.
