Product Overview

Like its predecessor, the AR637T features built in AS3X Technology, but now pilots can set up and program SAFE Technology to their aircraft. AS3X Technology (3-axis stabilization) works behind the scenes to smooth out the effects of turbulence so you enjoy a sense of stability and precision that makes it feel like you're flying a much larger, expertly tuned aircraft. SAFE Technology offers an extra level of protection so that RC flying is easier than ever before. When activated, bank and pitch limitations keep you from over-controlling and automatic self-leveling makes recovery from risky or confusing attitudes as simple as releasing the sticks. Programming and set up of AS3X and SAFE is done directly from your Spektrum transmitter* with an easy 3-step forward programming initial setup. To use SAFE and AS3X technology with the AR637T receiver, the receiver needs to be set up with a compatible Spektrum transmitter. With forward programming there is no need for apps or cables to program or make changes while at the flying field.

The AR637T features full range telemetry with an integrated barometer to provide altitude and vario telemetry data without additional sensors. Additional telemetry devices such as voltage sensors can be connected to the volt port and XBus telemetry sensors can be connected through the XBus connector. It also features an SRXL2 port for an SRXL2 Remote Receiver to add additional RF path redundancy (sold separately). An SRXL2 port is available to connect compatible devices, program and update the receiver, and bind with a traditional bind plug or connect a battery. The AR637T is compatible and ready-to-use with the Spektrum Smart ESC for even easier one-wire telemetry data. Spektrum Smart ESCs combine plug-n-play simplicity with the ability to communicate with other Smart electronics – together, creating the best-performing RC system for your model imaginable. For more information about Spektrum Smart technology please visit the Spektrum Smart Technology Page.

The AR637T receiver throttle port includes Smart Throttle. When equipped with Smart Throttle the standard servo connector delivers the throttle signal to the ESC, plus the ESC can send telemetry data back to the receiver. The throttle port will automatically detect when a Smart throttle compatible ESC is plugged in and the throttle port will begin to operate in Smart Throttle mode.

No more bind plugs! Instead, a large bind button is used to enter the bind mode. All combined the Spektrum AR637T gives you more in a 6-channel receiver than ever before, so that you can fly with the highest sense of confidence possible and have more fun.

Please Note:The DX7S and DX8 Gen 1 Spektrum Transmitters will not display Altitude or Variometer telemetry with the AR637T receiver.

Exclusive Spektrum™ AS3X® technology enhances flight stability by countering the effects of wind, turbulence, and other outside forces to help your aircraft fly smoothly and with precision. You’ll feel like you’re piloting an expertly tuned model that performs exactly as you want.



You can configure the AR637T receiver wirelessly, directly from any compatible Spektrum™ transmitter, through the Forward Programming menu. No separate computer or mobile device is needed for setup and adjustments.



SAFE® (Sensor Assisted Flight Envelope) technology flight modes help pilots avoid over-controlling their models. SAFE uses AS3X to deliver normal flight performance, but with limited bank and pitch angles to prevent the aircraft from getting in extreme attitudes.



Sometimes called a bailout mode, Panic is a SAFE Stabilization mode that can return an airplane to level flight from any attitude. It is usually assigned to a momentary button.



To enjoy the full benefits of Smart™ technology, use the AR637T receiver with a Smart ESC and telemetry capable Spektrum DSMX® transmitter. Vital telemetry data such as current, voltage, temperature and RPM is sent directly to your transmitter in real time. For more information on Smart Technology please visit our Spektrum Smart Technology page.



The Spektrum™ AR637T receiver features an integrated barometer (built-in pressure sensor) to provide altitude and vario telemetry data without the need to purchase additional sensor modules.

Answered by: Ben @ Wheelspin Models

Hello, Can I use a Spektrum AR637T 6 Channel SAFE and AS3X Telemetry Receiver with my Spektrum DX7S and a Park-zone T28 1.1? Can flap function be assigned to safe? Thanks, Paul
Asked by Paul on 10th July 2020

Yes, this would bind to your DX7S if it has a DSMX logo. It's 6 channel though - not 7

Answered by: Ben @ Wheelspin Models

Hi can you put this in any 6 channel plane or under do you have to download anyting or can you just put them in any plane?
Asked by Shaun on 11th August 2020

Yes this will work in any plane

Asked by Colin Summers on 21st September 2020

Yes that should be fine in pretty much any model

Answered by: Ben @ Wheelspin Models

Is this receiver a follow on from the older AR636A receivers with programming possible via a usb lead.......But with Tele functions...... and do you know if this is still programmable through the usb and a pc using the software or is it only done by forward programming directly from the NX series transmitters
Asked by Stephen on 14th March 2021

Yes, this is the updated version.

These are forward programming only

Answered by: Ben @ Wheelspin Models

Is the AR637T compatible with the Spektrum dx6e Transmitter, I'm hoping to create a SAFE environment for stability. Thanks
Asked by Martin Quinn on 10th May 2021

Yes, if your DX6e has a DSMX logo it will bind 

Answered by: Ben @ Wheelspin Models

Can I use this with a dx7 transmitter?
Asked by Grumpy on 18th June 2021

Sure, so long as your transmitter has a DSMX logo this should work

Answered by: Ben @ Wheelspin Models

Can this be used with a spektrum GPS module
Asked by Wolf on 11th October 2021

The manual says you need SPMA9587 for use with this unit.

Answered by: Anthony @ Wheelspin Models

Is this receiver compatible with my JR DSX9 transmitter.
Asked by R Deakin on 13th December 2021

Yes, this will bind to that transmitter as it used DSMX.
