Rescue changes pitch direction in flight

[Bischi]

Hello Spirit Users

At the check before the flight the rescue direction is correct.

At the check after the flight the rescue direction is wrong.

In the videos you can see what happens when the rescue operation.

During the flight, you notice nothing of the change, the helicopter flies perfectly

Does anyone else have this problem or has a solution to the problem?

I hope someone can help me.

Hello ZeXx86

I have already checked the page but can not find a solution.

Why does the direction of the rescue change during the flight?

I fly about 6min and no hard 3D, only curves, rolls and loops.

I have some Spirit in use and the problem is only with 2 Helis.

The problem with the logo 700 occurred only today. 50 flights and nothing was changed at the heli.

Run the spectral analysis and check the vibration level on the two helis with the problem.

[Bischi]

The vibrations are in the normal range.
On average below 10% with some short peaks of 21 - 26%

[ZeXx86]

Thank you for the details. Was the measurement performed with tail blades on? Or ideally in-flight? Measuring Y axis should be enough.

[Bischi]

The measurements are in flight, records of the spirit

[ZeXx86]

Great, so it was Realtime measurement, not from Telemetry.
In that case it is not caused by vibrations.

Do you use some fan on the ESC?

[Bischi]

Yes on both the original Kosmik cool fan

[ZeXx86]

As you can see in the guide I have linked to you, one reason for rescue being imprecise could be due to running fan.
Some fans could disturb unit so that it is loosing its precision.

Behavior that it is working at the beginning but will become worse during flight time is very normal for all described points at the page.

But you can always safely verify if it is working properly as described at the page.

Could you disconnect fan without a risk of ESC overheating?
