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.

 

Please Note: These transmitters do not support Forward Programming devices: DX6i, DX6G2 (EU Version), DX7, DX7S, DX7SE, DX7G2 (EU Version), DX8, Non-computer transmitters

AR637T Setup Series


 

AS3X® TECHNOLOGY (3-AXIS STABILIZATION)

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.

 

FORWARD PROGRAMMING

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® TECHNOLOGY

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.

 

SAFE® PANIC RECOVERY

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.

 

SMART TELEMETRY

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.

 

INTEGRATED BAROMETER

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.

Charges well and is sturdy and secure.
Color: PINK
This has been working really well for me. I have it mounted on my dash and not the window and it is very sturdy. My phone charges well with this and it has never dropped my phone and doesnt wiggle with car movement do it is very sturdy compared to others iv had in the past. Easy to remove phone and put phone in without having to adjust size every time. Great for delivery drivers. I haven't used the vent mount and don't see the need for it.

Charging phone holder
Color: PURPLE
My man loves this. He says it helps when he drives incase he needs a different route and his phone is needed. It is easy for him to use and fits his cellphone well. It seems to be very durable and keeps the phone stable and locked in place.

Well-designed but might not fit smaller phones
Color: BLACK
This is a very nice product. My only complaint is that it is not well-suited for my older Samsung S22 phone, because the phone sits so low I. The cradle that its power button is inaccessible. I solved that by fastening a small spacer onto the bottom edge of the cradle, and now it works very well. It would be a better product if the bottom edge of the cradle could be adjusted. Aside from that minor issue, it automatically grips the phone and holds it firmly, and there's a built-in battery so the ungripping process functions even after the ignition is turned off and power to the cradle is shut off.

Works Great
Color: BLACK
I really like the automatic closing feature when my iPhone is placed on the charger. I have a Pro Max and I thought the phone might be too heavy for the clasp and would move while driving. I have used both the suction cup and vent connector to hold charger and phone without it moving. The device also must have a capacitor or battery, as when the power is off to the holder, you can still press the release button and the charger opens to release the phone
