    • 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.

WHAT A MISTAKE THIS WAS! EXTREMELY SOFT, OFFERING NO SUPPORT AT ALL!
Size: Camping(Pack of 1), Color: Original White, Size: Camping(Pack of 1), Color: Original White
INITIAL Impression: WHAT A MISTAKE THIS WAS! The foam is taking forever to expand, it is a gross color, it is way too soft where it has started to expand. The warranty says it ONLY applies to the original purchaser, which means you cannot give this to anyone as a gift, it would instantly lose its warranty. DO NOT USE ANY EXTERNAL HEAT SOURCE (some memory foam actually suggests putting it in a slightly warm dryer, but to do that would void the warranty.) I got this because I have severe back pain, but it doesn't look like it will ever be firm enough to offer support. It says it will take 24-48 hours to fully expand! I bought it because I need relief NOW, not in 2 days! It has a very limited warranty of only 3 years. The memory foam travel size pillows I bought on Amazon, made by MALOUF, in 2017 came with a 5 year warranty and are still useful, but do need replacing, 9 years later! Unfortunately those pillows are no longer available on Amazon. I chose this small Vaverto memory foam pillow "for camping", because it was available with next morning delivery with some other purchases I made yesterday. (Hoping to be able to use it TODAY.) And because most of the reviews were positive. It says on the crumpled paper warranty and directions, that ONE side of the pillow is for cooling, but WHICH SIDE? They don't tell you. The order "Shipped at 12:31 AM" the box was cold when it was "Delivered at 9:41 AM". The outdoor temperature had climbed to 51 degrees by then from a low last night of 47 degrees. My room is heated to a comfortable 78 degrees. But we still have a long way to go before this hunk of greenish blue, extremely squishy (I can pinch it at the most expanded area and my fingers nearly touch each other with maybe ¼” of foam separating them. NOT an encouraging sign. There are bits of foam starting to come out of the "punched holes" which appear to be slightly smaller on one side than the other, but WHICH is supposed to be the "cooling side that dissipates heat? Probably the larger holes, but they also weaken the firmness. On closer examination of the crumpled paper that came with it, it says '"TWO-SIDED COVER FOR VERSALITY" Then in a tiny diagram next to that, it says "COOLING SIDE DISSPATES BODY HEAT" with Dissipates spelled wrong! Where is this thing made? Ah.. "CHINA" on a severely crumpled tag inside the cover. It also says the cover is “70% Polyester 30% Viscose Made from Bamboo”. But the Photo shows "Bamboo" in large green letters on the cover along with "VaVerto" in much LARGER grey letters above that. The only letters on my case are the bottom part of a "b" with two "oo" next to it, in a grey-green color, extending from the side seam. NO actual WORDS at all. And the cover looks identical on both sides. Okay, it's been well over 4 hours in a very warm room, now 80 degrees with the sun pouring in, and it has mostly expanded, but I can still almost touch my fingers together when pinching the thickest part of the pillow, there is still only about ¼” of foam between my fingers. I would describe that as EXTREMELY SOFT. In the actual description of the product, on the Amazon page, if you open the "Features & Specs" it shows "Item Firmness Description - Medium" NOT what the headline says for the product: "Vaverto Small Memory Foam Bed Pillow for Camping - Compressible Medium Firm, Breathable Cover, Machine Washable, Ideal Backpacking". If I weren’t bedridden in a nursing home this would go back immediately, but it is very hard to get the staff here to help me return ANYTHING that needs to be taken to a store or kiosk. So I may just be out $22.07. FINAL Impression: WHAT A MISTAKE THIS WAS! EXTREMELY SOFT, OFFERING NO SUPPORT AT ALL! (PHOTOS ARE NOT ACCURATE to the product!!)

Comfy, but not Cooling
Comfy for a stomach sleeper, but doesn’t stay cool as promised by other reviews.

Meh. Not impressed but not the worst.
Size: King (Pack of 1), Style: Single Pack, Size: King (Pack of 1), Style: Single Pack
TL;DR: Not worth the money I’ve had quite a few cooling pillows and, while not the worst, this is also not the best in my experience. First, I had to take the cover off. It was ridiculously thick, thereby negating any cooling effect that I could feel. With the cover removed, the cooling sensation is noticeable when laying your head on it and it lasts for a minute or so. On the bright side, when the cooling feeling completely dissipates, the pillow doesn’t feel hot like some others. Having to lay on it without the cover makes it less comfortable because of the encasing material. Other than that, I’d rate the support and comfort as mediocre as well. Not worth the money in my opinion, maybe if it was about 33%-50% less.

Firm yet comfortable
We have purchased several of these pillows over the past few years. They have held up well and held their shape and firmness, even with washing. They are the right height for neck comfort and we do not need to double up pillows anymore to get a good night's sleep. They are also a good firmness to rest against while sitting up in bed.
