FlyingIron Simulations has issued another update for their Spitfire Mk IXc for Microsoft Flight Simulator. Hotfix 2 includes several flight model fixes, after the flight model had changed a bit with Sim Update 5. The developer has also enhanced some of the flight characteristics to make them more accurate with the real life version of the plane, such as enhanced drag, tunes stall speeds and the torque factor during take-off.
- Fixes adverse SU5 impacts to the flight model
- Accurate zero-drag coefficient (factory data) … translates into correct top speeds
- Improved drag on flaps as well as gear
- Induced drag tuned
- CG completely redone using factory data
- Pilot weight now 215 lb (170lb pilot + parachute + dinghy)
- Verified and tuned stall speeds (full tanks with clean and landing configs)
- Tuned p-factor / torque for a natural takeoff that can match the original POH (full right rudder trim, 1 notch down with boost 9 or no trim at a more gentle boost)
- Fine tuned roll rates at various speeds
- Tuned turn rate
- Adjusted elevator setup based on pilot accounts…now requires a tiny bit of DOWN trim to fly straight. Also take off with 1 notch DOWN trim, as per POH. This makes it easier to lift the tail around 50-60mph.
- Elevator trim much easier and more stable during flight.
- Engine and propeller adjustments to counter for a bug/change in SU5 that handicaps the RPM authority at altitude
