So I'm the friend, been flying the F1 with a HOTAS & rudder since the module was released in pre-release, and my trim works just fine.
I can read this last .trk just fine, and so I believe you guys at AERGES should too.
However, there is an inconsistency in the way the trackfile itself plays between Chokaa's side and mine: on his, neither the physical stick inside the cockpit (apart from the Trim hat moving) or the outside control surfaces are affected by trim. (I know this from watching a screenshare of the issue over discord).
When I watch this track, however, both the stick and control surfaces move. I believe this causes some glitch inside DCS, with a mismatch between the position of control surfaces and the aircraft's behaviour. I believe that is the cause for quite drastic stutters that I experience while watching this track, and that you guys may also see.
Thanks for your time
