That's the weirdest thing about this game. The purpose of trim is to relieve stick forces at given configuration and aoa so you do not have to maintain pressure and when consequently initiating a directional change you do not have to first overcome current resistance/force, i.e. flying around with stick help in your lap then u have to pull even more. In this game it seems to help you turn even faster which puts you in a bad trim position when you come out of the change in direction. In RL you would roll off the trim as you ease the stick forward to counter the forces on it/you
So in game, I use my hat switch to apply and remove trim as needed as in RL, almost as a mini stick, pop flaps push forward on the hat i.e. pilot wound on approach, I trim long glide slope at 125 indicated and apply throttle to adjust touchdown point, if i pass out it lands itself anyway), in a fight the hat trim down helps the nose to come around smoother, but it doesn't reallly get pointed in the right direction and i end up pulling more stick unconsciously. really obvious in the f4... but then i need a lot of practice in it
