I found these two values in the SDK:
https://docs.flightsimulator.com/html/Content_Configuration/SimObjects/Aircraft_SimO/engine_cfg.htm
[PROPELLER]
| Parameter | Description |
|---|---|
| prop_mod_lift_efficiency_cf | This is the propeller surface induced drag coefficient. |
| Default value is 0.5. | |
| prop_mod_zero_lift_drag_cf | This is the propeller surface based drag coefficient. |
| Default value is 0.01. |
Has anyone played with these two see what effect they have?
The 414 doesn’t even have modern prop physics enabled, and these values require this first.
| Parameter | Description |
|---|---|
| prop_mod_use_modern | When set to 1 (TRUE) the simulation will use the modern version of the propeller model, instead of the legacy version. This means that the parameters prefixed by prop_mod_* will be used instead of - or in addition to - the equivalent parameters to determine the behaviour and effects of the propellers on an aircraft. |
| Default value is 0 (FALSE). |
Posted my findings to another thread more relevant to this specific topic. Those interested can continue this line there:
