Actually, it's the other way around -- Mi-8 and Mi-24 autopilots should work differently. Unlike in Mi-8, In Mi-24 pressing the trim button should center autopilot at this new location of cyclic. But in the sim right now autopilot works incorrectly.
Currently, when you press the button autopilot channels reset to the neutral positions as they should, but after you release trim button they return to the previous state, which causes unintended movement. You can see that at autopilot indicators -- when button is pressed bars should go to their neutral positions and stay there, but right now they move back the moment button is released, causing pitch and bank to fluctuate.
