Unfortunately the spike is still very high. I am afraid it look like vibration problem.

There is chance we can make it work also with these vibrations. We are working on new improvement where vibration level will not play a role also in GeoLink features.
So this can be helpful. But the best would be to bring the vibration level down. The spike coming from the tail should be at least 2 times lower.
It might take 1-2 weeks to make it work even in this condition.
I will swap out all the tail drive gear and test again today.

This is with the new unit you sent.

We are testing new improvements for GeoLink features and Coaxial mode with a high vibrations.
If anyone is interested in the firmware, please let me know.

Hello Tomáš,

I am interested in new GeoLink software because I have nearly the same behaviour as reported here when I try to use PosHold.
I have to constantly give some nick foreward and roll right to keep the heli in position. With stick in middle position it drifts away rapidly backwards and to the left.

At me vibrations should not be the problem - analysis tells me "good" on all three axes even with tail blades on.
Heli is set up very accurate (using "soko-heli-tools") and is flying very stable for example in coaxial mode.

Regards,
Toni

Hello Tomáš,

I did some tests with the new firmware and yes the heli is a little bit more stable now, but I have still to correct the position with nick forward and roll right.
Not so much as before, but without correction drifting away is still present.
Additionally I changed the main rotor blades and used different RPMs, but the result is always the same - heli moves backwards to the left without corrections.
Another point: today I had constant blinking of the GeoLink Led after one of the flights - static discharges shouldn't be there because I use no beltdrive and all carbon and aluminium parts are connected.

Thanks for your support,
Toni
