@hpgbproductions it is, when i place it, its facing the right direction, i was thought maybe the gyro was orienting itself by something else to decide wich way is up pf the aircraft..
for now, low stability and speed is quite enough, i just cant make the speed too high

Is the gyro itself upside-down on the plane (i.e., actually un-rotated)? The gyro will try to align its local Y axis to the global Y axis.
If not then idk, maybe there is a bug or edge-case behavior with upside-down gyros

My next idea would be to save your current craft. Open a new airplane file and see if gyros act the same way in there. If they act right save your current craft as a sub assembly and drag it into the new airplane file

@ArmouredTrashCan yes, one cockpit only, and no rotation

@griges I see the only reason I could think that would happen is because your cockpit is upside down. Other than that I'm not sure. Make sure you only have one cockpit

@ArmouredTrashCan nope, pure stock gyro... and its going upside down not because input, because the gyro thinks the craft is upside down

Do you have a funky tree input going to the gyro?

I would start by spawning in a new cockpit piece. Then I would check your controls and make sure they're not maxed out one way or another. If that doesn't work I'm not sure what you would do from there
