Hello,
on my helicopter I have installed the Spirit 2 (sw version 3.4.1) and Geolink V2 (sw version 1.3.0) control unit.
I tried to upgrade to version 3.4.3 on Spirit 2 and to 1.3.2 on Geolink but, when Geolink engages the GPS, the collective lever no longer works.
Returning to previous versions, everything returns to work.
May you please suggest a solution to my problem?
Thank you

Hello,

have you read ChangeLog for version 3.4.2 and 3.4.3? If not, then I recommend to read it, because there is decription what was changed and what behavior is different in the update.

Very likely you are trying to start your helicopter with some GeoLink function activated, which is not good.
This GeoLink function is very likely Return to Home. Return to Home can return also to a specified altitude now. So it is changing also Collective pitch.

It is enough to open Diagnostic tab and see what GeoLink feature is engaged and use switch to turn it off. Please always read ChangeLogs before updating.

Hello,

the problem was on the values of the switch of the "Altitude limit" function so it was always on.

Thanks for your help.
