They have something like elasticity_table for every control, just needs to be managed properly, I think. From their SDK:
"A table that allows you to scale down the elevator control surface deflection angle depending on the current dynamic pressure. The table has a maximum of 5 values and has the following format:
dynamic_pressure:correction_factor, dynamic_pressure:correction_factor, etc…
Pressure is expressed as [psf](file:///C:/MSFS%20SDK/Documentation/html/Content_Configuration/SimObjects/Aircraft_SimO/Flight_Model_Definition.htm#) and the yoke correction factor is a [Percent Over 100](file:///C:/MSFS%20SDK/Documentation/html/Content_Configuration/SimObjects/Aircraft_SimO/Flight_Model_Definition.htm#).
The dynamic pressure being airspeed dependent, this allows to reduce deflection based on speed. Dev Mode aircraft debugging tools allow you to get the current dynamic pressure. The dynamic pressure can also be obtained with the following formula:
dynamicpressure = 0,5 * airdensity * airspeed * airspeed
Default value is: 0.0:1.0"
