MS controller settings were good and flight mode is modern. Situation replicates with Cub, 172, Baron, and CJ4. Gentil banks left or right work fine all around a circuit and random flying. Can bring yoke (ailerons) back to center and hold ten through center to a gentil right bank and back to hold center - smooth as glass. However, a bank either way that goes past “gentil” - not even a steep bank - there is a twitch (jerk) and then return to center sets up series of oscillating, uncontrollable banks LR - RL followed by nose to the ground. Have tried so many sensitivity combos that I don’t think the solution is in the settings.
