You roll in a turn fight when you stall one wing first, generally from adverse yaw. The correction for adverse yaw is with the rudder.
I thought it was a reduction of lift with aileron up vs increase of lift with aileron down, with the rudder input to keep the turn coordinated, it is adverse when you fail to use the rudder creating a skidding turn which raises the stall When a plane “stalls” loses all lift, it will drop the same wing it drops in level flight. As an example a crop duster was doing a hard right climbing turn when it stalled, the left wing dropped and it went down in a left spiraling turn.
It seems to me that if a wing was heavier it would take less deflection of the ailerons to reduce lift on that wing, lift force perpendicular to the motion of the wing, which is greater than the downwards gravitational force on the wing and so keeps the aircraft airborne. I could be wrong I reckon, but it seems to make sense, the heavier a wing is the less disruption of the airflow, (increasing drag) it would take “stall it” as you put it. Although when you lose half a wing in game, you either have to go fast with right aileron and rudder input to correct for the drop of the wing with less lift, reducing lift on the good wing as it were, but to land you have to slow down and go full flaps to maintain control and if the broken wing (Less lift) is on the torque side it’s chop the power and all the opposite rudder you have to keep it level. If on the opposite side, I add power using torque roll to bring that wing up. A way to test this in game is to drain a tank one one side, reduce thrust to zero and see if said aircraft rolls off the same way it would with full fuel.
