Missing log "2025-09-24_3rd Flight Part 2_18. log.4dr."

Hello ZeXx86,
I was flying my Goblin Kraken 580 again today, and on the very first flight, the altitude limit was triggered again after about 25 seconds. Please see the attached log file 22.log.4dr.
The helicopter was at an altitude of about 26 meters, and in the log file, the altitude suddenly drops to zero.
Firmware 4.0.1 is currently installed.
I ordered both the Spirit GT and the Geolink V2 directly from your online shop on October 29, 2024, Invoice No.: 240012865, and this problem has been occurring since April 8, 2025.
How can we finally solve the problem? Flying like this is no fun.
I would prefer to send the Geolink to you for inspection and, if necessary, exchange.

Hello,

we will ship you new GeoLink for comparison. If the new one will work well it is clear.
Presently it look like GeoLink resets mid-flight. But why it happen is unclear, there could be more reasons from static discharge to a faulty solderoning joint.
Thank you for all the logs.

Thanks, I'm curious to see if that helps.

Hello ZeXx86,
I swapped the Geolink on both my helicopters for verification purposes and flew both today. As expected, the other helicopter, the one with the defective Geolink, now has the problem.
So the new Geolink that was sent, should also fix the problem.
Thanks Thomas

Hello Zx86,
the new Geolink arrived and I completed four flights with it today.
Everything is OK!
I tested everything where the old Geolink incorrectly triggered the altitudelimit.

Where should I send the old Geolink back?
Perhaps the problem can be found.

Many thanks for your support!

We are very glad it was finally resolved. In this case it was really hardware problem.
