sze5003: I'm only replying with this because you mentioned "bottom right" for sim mode, and you might be looking in the wrong area.
If you're at the main menu, click the gear at the top "Options", at the next screen, click the Gameplay tab, top left options for difficulties... Game Flight mode and Game avionic mode. Those need to be unchecked.
Otherwise, you may be referring to the "slow" trim issue...Where it works, but it works slowly.
