So first off this little guy works as designed and is a really good value. Foreflight connects right up with my iPad and
myself and my CFI both will connect to it for traffic alerts.
AHRS works great too... i had a real world vacuum pump failure at night, so I switched on my attitude display in foreflight which was a great safety net.

Things to keep in mind though, and I don't want to discourage what you are getting out of this device for the tremendous value that it is, but do keep these in mind on what you give up though by not going with the more expensive alternatives incase you are daily instead of weekly like me:

1. Needs an external battery, and the connector on the raspberry pi in the unit is weak. This isn't the fault of the assembler, the pi's the micro usb connector isn't very robust. I've been using mine for 6 months now and this connector has loosened up and prevented my device from receiving reliable power. I finally pulled it apart thinking i'd have to replace the raspberry pi in it and i was able to bend the connector back into shape and spare it. Thankfully if I do destroy the connector, a replacement PI is cheap and easily swapped.

The higher dollar units with their internal batteries do not run into this.

2. The fan has gotten extremely loud when its running...sounds like the bearing is shot in...not sure what the quality is of the fan that comes with it (sleeve bearing perhaps?) but i'm looking for a replacement fan though. Not sure if the higher dollar units even have fans, if they don't then definite ding here.

3. Obnoxious Antennas. They stick out, take up space in my flight back, take up space on the window. Higher dollar units with their integrated antennas don't have this issue.

But dollar for dollar, a great value, with these weaknesses I'm only knocking 1 star off because of the great value this device is.

The image shows everything that came in the box.
The Stratux itself.
A suction cup mount with six total cups, two extra after mounting the four to the mount.
Two antennas, one for each frequency.
A power cable with button to make turning the Stratux off easier.
A 10Ah battery. (Actual capacity measured to 9.3Ah)
A strap to strap the battery to the Stratux.
A micro SD card reader to reflash the micro SD card that is already in the Stratux.

The Stratux came with the latest firmware and worked without issue right out of the box. Make sure to put your phone or tablet in airplane mode then turn on WiFi and connect to the stratux wifi to configure the device as well as change settings.

The battery is different than the one shown in the image. The one in the listing uses a 6Ah battery with a built in cord. The one supplied is a 10Ah without a built in cord. To replace the built in cord, they have
included a cord that has a power button.

This new battery holds about 9.3Ah as seen in the image bottom left.
This new battery has USB C to charge however it does not seem to have a USB C controller as it charges at 5V 2A just like the USB B Micro does. Further, this battery cannot charge a USB C device via the USB C port. Only the two USB A ports offer charge. Considering the use case for this battery of powering the Stratux, it is good enough for the job.

While I doubt it is required, it is possible to gracefully shutdown the stratux using the UI by connecting to the webui of the device itself. It is a small computer after all and shutting it down gracefully when possible couldn't hurt.

I just started training for my pilot's license and already have a pile of expenses (outside of the niceties). One of the items on my "wish list" was a Stratus 2S, but being a student pilot, I couldn't justify $800 for it. After doing some research and digging, I found the Stratux project. While I'm fairly adept at putting together Arduino, and Raspberry projects, this was one I wasn't willing to take on, basically because I don't fully understand everything that goes into it. So, I opted for a pre-built unit from Crew Dog. For 1/4 the cost of a Stratus 2S, I got a unit that works flawlessly with Foreflight, allowing me to record my flights so I can export them to Cloud Ahoy and debrief later. It's so nice to be able to watch a lesson I did last week, just before my next lesson. It really helps keep the information fresh. I wouldn't be able to do that as effectively without the Stratux unit.

Since I'm a student, I don't have my iPad in the cockpit when I'm flying. Here is what I do: 1) as I'm doing my pre-flight of the aircraft, I turn on the Stratux and place it on the wing so it can start gathering satellites (signals? whatever the proper term is) 2) when I'm finished doing the pre-flight walkaround, I place the Stratux on the window 3) grab iPad from flight bag, and go to the Stratux page 4) level AHRS & calibrate gyros 5) Open Foreflight and click the record button 6) throw iPad back in flight bag 7) go fly. Last, when we land, I stop the track recording in Foreflight, turn everything off and pack it up. Then when I get home, I'll export the track log from Foreflight to Cloud Ahoy. Works great!

My only "complaint" was the unit doesn't come with a carrying case. If you're like me, your flight bag isn't the safest place to just drop the naked unit into. So, I purchased this case to keep it in: CO2CREA Hard Travel Case The antenna's need to be removed to fit, and are just a hair too long, so as you can see from the picture, you'll need to bend them at the joints to fit perfectly. Now, I can put it in my flight bag without worry about it getting damaged.

Reception isn't very good. It might be where I usually fly though. (Northern NV)

This ADS-B Receiver is excellent. The only complaint that I have is that the box doesn't come with any instructions except for the power bank. Most people will watch a YouTube video to get it setup, but a detailed instruction manual regarding features, how to setup, the functionality, etc. would be great.
