    Practice with the Stirling

    I spent a bit more time over the last couple days (between other projects) editing the flight model of the Stirling.
    Very early on, I found that substituting the Propeller Power Coefficient Table...

    Hello Hubbabubba,

    Keep in mind that the kind of Magneto Switch installed may have varied from one version of the aircraft to another.

    Hello Hubbabubba,

    The Gauge for Engine 3 and Engine 4 is done. It was pretty trivial and really a matter of find and replace in the code.

    This was the first test of the B-5 Magneto Gauge.
    The Mouse Areas appear to work fine.

    Type B-5 Dual Magneto Switch

    Right after I finished the Fuel Gauges for the P-47, I was bit encouraged by the fairly rapid progress.
    In the next day and a half, I created a full set of bitmaps for a Type B-5 Dual Magneto Gauge....

    New Gauge is complete.
    162 Gallons in the Main Tank (60%) has quite a different appearance.

    Duplicate of Stock P-47D Fuel Gauge

    Here is a close up view of the Pointer for the Main Fuel Tank.
    It can be seen from this view why there really SHOULD be a Mask included in this gauge.

    When working on updates to the P-47D-25 that has been stuck in Ivan's Workshop for a while, I came across a very slight problem.

    P-47 Fuel System Differences

    The attached diagrams show the differences between the fuel systems in the early and late D model Thunderbolt.
    The stock fuel gauge is clearly incapable of reading the larger quantity.

    There are quite a few things that can be done to tune the cruise performance of your aircraft.
    I work with CFS1, but the principles should be the same.
