reported F/A-18C - Trim Bug when inverted

[Guericke]

The hornet's incremental trim does the opposite of what it should do after a certain point when inverted. From 0 to almost halfway to the red cross on the trim (Fig. 1) it works normally, after that (Fig. 2), even at full stick deflection, the hornet trims the nose up instead of trimming the nose down, and after even more trim the FCS does not recover (Fig. 3). And if you don't bail out or the trim goes in the opposite direction, it will continue until it crashes. This used to work very well, to the point where you could trim the plane upside down to stay in the horizon line without any stick input. It's very easy to reproduce, just go inverted and play with the trim, after the point where the aeroplane starts to dive towards the ground, just trim the nose high and it will recover. I don't think it should work that way. I haven't tested other things related to trim, so I'm not sure if this is a bug just for this scenario or if this is part of a bigger thing related to trim and FCS.
