Spirit System

The geolink has a setting that allows pos hold altitude to be adjusted by moving the pitch stick.
(This can be disabled in settings.)

What I think is happening is when 1st engaged, spirit sees stick at above centre (because we're hovering) and thinks we're climbing so start depending. Realises its falling and starts climbing again, then settles down to a hover.

Maybe? But that's just a guess. Tomas can answer why it drops when 1st engaged.

Which is correct mounting for Spirit? The blue version show the describe in Heli Manual

As per manual. Servo arm 90 degrees to servo.

Yes, blue is correct. This mean it is way too off at the photo. This can degrade flight performance and GeoLink functionality in all Altitude related functions.

I have changed servo konfiguration, replaced some ball bearings and shafts. The heli flies beteer than everywhere. Now it‘s all o.k.
