As Wotan said, your "tilted" attitude is because the dash requires some rudder trim in flight - the Yaw Damper is rather ineffective in this plane. (One of the many things I learned in the Airline2Sim training).
FSX - Majestic Dash 8 Q400
In most turboprops with non-counter rotating propellers its the same principle. The aircraft will react to power changes all the time, some are benign (like kingairs, dash 8 300/100), while others are rather aggressive, needing frequent retrimming (q400, i heard cheyennes as well and mu-2s). 2ff7e9595c
