Sim Update 4 (SU4) version 1.6.29 just dropped for MSFS 2024 — and today we’re testing one big question: Did they improve the CFD and flight model?

In this video I take the Cessna 172 out for a full test flight to check:
Stability in pitch & roll
Rudder & slip behavior
Ground effect
Updrafts & downdrafts
Turbulence response
Crosswind handling
Overall “feel” of the aerodynamics

I’ll show you exactly how the aircraft reacts in different conditions and whether this update actually changed anything meaningful in the flight model.

If you’re trying to understand whether SU4 1.6.29 brings real improvements — or if the CFD still feels the same — this video will walk you through everything I found during testing.

Let me know in the comments if you feel a difference in the flight model after updating.
