Sorry, I'm not sure what you mean. Shall I connect the ESC by using an Y-Cable to both, Receiver and Spirit GT Channel 1

No.
Open the software, then in General - Channels assign Throttle to Channel 1.
Save the settings.

This should resolve your problem.

Connected to CH1 is Pitch/Aileron servo.
Regarding "manual.spirit-system.com" the port AUX1 shall be used for BEC/ESC and AUX2 for second BEC line.
Is this correcht? Do you mean this?

Unfortunately no, I dont meant this.

I only meant to do these steps:
  1. Open the software
  2. Go to General - Channels page
  3. Assign Throttle to Channel 1.
  4. Save the settings.
Nothing else is required, no wiring changes are needed. There is no relation to wiring. only channels.

OK, then the ESC line stays connected to Receiver?

Hello,
Unfortunately, setting channel 1 to throttle didn't make a difference. I flew once yesterday, and the altitude limit was triggered again.
I'm attaching the flight log.

Hello,
I updated the Spirit GT today from version 3.7.2 to version 4.0.0. I set the recommended rotation speed and rudder delay values ​​​​from the update description.
I also reinstalled version 1.4.1 on the GeoLink v2, which took about 10 minutes, not 75 seconds.
After that, I flew twice without the altitude limit being triggered uncontrollably.
When the minimum altitude was exceeded, it was triggered as intended.
I don't know the reason now, but I hope it stays that way!

On Wednesday, I finally got back to flying. I made three flights, the first and second of which went smoothly.
On the third flight, the altitude limit was triggered again during a flip. I turned the function on and off several times, but each time I turned it back on, the helicopter climbed away.
Then I landed, turned off the engine, and restarted, and everything was fine again. The altitude limit could be deliberately triggered by falling below the minimum altitude, and it automatically deactivated again after gaining sufficient altitude.
This time, I couldn't find any abnormalities in the Altitude-Tab in the logs "2025-09-24_3rd Flight Part 1_17. log.4dr" and "2025-09-24_3rd Flight Part 2_18. log.4dr."
