Steam analog King Air-Trim completely false before taking off

Although I scrupulously followed the checklists and had chosen no failures in the weather radar screen, it has already happened twice to me that the trim has moved itself at the maximum nose-up position before take-off. Is this a bug or how to fix it?

@ericj51 I haven't encountered anything like that. For sure not happening with any other aircraft? I initially thought of a controller or keyboard bind setting the trim when you don't expect it.
