Odd problem with GR6 telemetry

[jure]

I remember having a similar drift problem with my receiver. I hated the altitude drift.
I solved the problem by removing the receiver from the package , and gently cleaning the PCB with a toothbrush and alcohol (IPA).
It works fine now.

How much is steady decent.

Here's a video of what I'm dealing with:

As you can see, the first time I power up and connect telemetry the altitude starts at a negative value and climbs. When I reset to zero, it starts descending. Repeated resets have the same result.

You did not attach the video.

Sorry about that. Fixed.

That’s a lot of variation. Heck, I pulled out the sensor app on my phone. Here’s the pressure graph from the built-in pressure gauge. Surely it can’t be that expensive. Even though it’s an iPhone 12 Pro I can’t imagine they exactly splurged on a sensor most people don’t even know is in their phone!

Note there is a very slow climb. The variations? That’s me raising the phone from my head, to my lap, to above my head, and back to my head! It’s that sensitive!

Note a change of 979.54 to 979.46 is a change of roughly 0.7 m. That seems about right from how I was moving the phone.

So that slow drift? 1/3 of a meter over 15 seconds. Again this is the sensor in my phone. I don’t know what it is but I can’t imagine it’s an expensive sensor! A vario sensor marketed as high precision should be better than my phone pressure sensor IMO.

Interesting never seen this sort of change of pressure / Alt change. I have a number of these receivers and they behave more like your Iphone.

I would suspect a receiver issue.

That is way bad - you must have a bad chip on that receiver. If you bought it from us, please email: contact@alofthobbies.com and we will need to get that one back and get you a nice new fresh one.

Sorry for the troubles!!

Thank you Wayne, I did indeed buy it from Aloft and I sent off an email to your team to arrange for the return. Appreciate it!
