    • Spektrum AR637T+ DSMX 6-Channel AS3X+ & SAFE Telemetry Receiver
    • Spektrum AR637T+ 6-Channel Receiver Overview

      The Spektrum™ AR637T+ 6 Channel AS3X+ Telemetry Receiver is a DSM2® and DSMX® capable receiver with a compact footprint to fit in a wide range of aircraft. The AR637T+ is a full-range 6-channel receiver with built-in AS3X+® and SAFE® stabilization. The all-new AS3X+ stabilization algorithm creates better flight performance, improved sensor accuracy and data rate, and provides pilots with a generationally different feel compared to AS3X. There is no delay in control response or limits on control throws. You'll simply feel like you're flying an expertly tuned model that does exactly what you want.

      AS3X+ and SAFE are programmed and set up 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 and an integrated barometer to provide altitude and vario telemetry data without additional purchase. XBUS, RPM, voltage, and temperature ports can be used to add additional telemetry sensors available separately. It also features an SRXL2 port for an SRXL2 Remote Receiver (SPM9747), available separately, to add additional RF path redundancy. An SRXL2/Bind/Program/Batt servo header is available to connect Smart devices, program and update the receiver, bind with a traditional bind plug, or connect a battery. The AR637T+ also features a bind button for easy binding with no plugs necessary, offers both SmartSafe™ technology and Hold Last, as well as preset failsafe types set through Forward Programming. Additionally, Smart Transmitter Model Files allows BNF models to be stored on the receiver to automatically setup the model at bind.

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

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

      See www.spektrumrc.com for the latest updates to your receivers and transmitters.

      NEXT GENERATION IN FLIGHT STABILIZATION

      The all-new AS3X+ features a vastly improved stabilization algorithm that has been rigorously tested by experts throughout the hobby. The system is even easier to tune and can be easily optimized for any type of aircraft you fly. Never again spend hours tuning and tweaking until you get your aircraft locked in. We've been able to set up most aircraft in less than five minutes including the first flight tuning.

      Key AS3X+ improvements include:

      • Stop Lock and Release Rate parameters
      • Heading Hold improvements
      • Improved gryo filtering
      • Canard and Thrust Vectoring support
       
      SMART TRANSMITTER MODEL FILES SUPPORT

      Smart Transmitter Model Files is a new feature on the AR637T+ receiver that makes transmitter programming the easiest has ever been. It consists of a set of transmitter configuration parameters that are stored within the receiver's model file. When binding to 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 one stored on the receiver. This will provide the user with an easy and simple way to acquire a transmitter model setup for their BNF model without the need to set it up themselves or search for and download the corresponding model online.

      Note: Supported transmitters currently are the iX20, iX14, and NX transmitters with the latest firmware updates.

       
      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.

       
      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.

       
      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.

Cute but Not Durable
Color: 2PK Green Leaping Phrog
⭐️⭐️⭐️⭐️ Cute but Not Durable Super cute toy—my dogs loved it right away! Unfortunately, they chewed the head off within a few hours. I ordered a second one because they were so into it, but the same thing happened again. I won’t be ordering a third, but they still play with their two headless frogs. So while it’s not the most durable, it definitely kept them entertained!

Great toy
Color: Black/Orange
This brand really makes durable toys. They outlast every other toy my dogs have. One dog loves to get the squeaker out of any toy, but he doesn’t rip this one apart. Obviously it won’t last forever, but no toy does! Some other brands of toys only make it a day or two, while these last months to years.

Great toy for two big German Shepherds
Color: Brown
We only buy Tuffy dog toys now because we have one German Shepherd, and we often watch our daughter's GSD too, and the two dogs tear anything else apart in minutes. Tuffy toys are BY FAR superior to any other dog toy we have tried. That being said, some Tuffy toys seem to last longer than others with the two dogs, and this one has been pretty good! We've had it for a few weeks now, and it's just now starting to show some white (stuffing) where their teeth have pierced the top of the toy. That's pretty good, considering they play tug of war with it and can tear into toys pretty hard. If it were just our one dog, I think it would last a lot longer because it's the tug of war between the two of them that does them in faster. Even so, when they do manage to tear the fabric in vulnerable places, I just pull the stuffing out from that area, and they continue to play with it, sometimes for months! This one is better than some other Tuffy toys too because it has lots of areas where there is already more fabric and reinforced seams than stuffing, like all the legs on the side, the tail, and even the pincers. So far, they haven't been able to tear into those at all. Just a bit on the top of the head, and so far, no stuffing coming out yet. This one is a big win for us! When they finally do do it in, I will turn around and buy another Scorch the Scorpion right away!

Tuffy Desert Phrog vs Lola
Color: Green Leaping Phrog, Color: Green Leaping Phrog
Just a little background about my dog. Lola is a 5 year old corgi-terrier mix with jaws of steal. Lesser stuffed toys have met death in under 5 minutes. Tennis balls last less than a day. Rope toys that do not have frayed ends might possibly last a week (frayed ends never stand a chance). The only toys that she has not managed to destroy are her Kong, a Kong bone, and a racquet ball. I figured I would document the life span of Phrog (Tuffy Scale: 9) before making my final judgement on it’s durability. Day 1 - Phrog Arrives! Lola was very excited about the arrival of Phrog and immediately went into destruction mode. Phrog did sustain a little damage before we were able to bribe her to drop Phrog and get her understand that he was more fun to play fetch with than to mutilate. The white you see in the picture is not stuffing, but the second layer of defense for the toy. The fact that my living room is not full of stuffing and I didn’t have to pry a squeaker out of my dog’s mouth, I’d say Phrog wins the Day 1 challenge. Day 9 - Phrog has sustained a little more damage, but not anything life threatening. His side wound is a little bit larger and one of his eyes is half ripped off. For safety reasons, I am going to finish removing the damaged eye and some loose thread from various places. Other than that, Phrog is still holding up and holds top toy spot. I have also found him very useful for dealing with anxiety; the squeaker can often distract her from her stressors and Phrog takes the abuse of her frustrations. Day 16 - Phrog is starting to show signs of mortal wounds. Lola has made it through the thicker layer around his arm and I can see the stuffing. It is only a matter of time before gets all the way through. Day 60 - Phrog still lives!!! I have done some surgery on Phrog to reinforce the fabric around his arms, but Franken-Phrog is still the favorite of all of the toys. She will even get brave enough to rescue Phrog from the evil vacuum when he is kidnapped and tortured. I am thinking about purchasing Phrog II for the inevitable day when Phrog goes off to the pet toyland in the sky, but for now, there is only one Phrog for Lola.
