I didn't spot this yesterday, but there is also an update (161MB) for the FSX SDK. I Imagine there will be a few changes in it as its 60+ MB larger than the previous SDK... fingers crossed there will be more in it for our developers.
Not had much time to investigate yet, but recompiling the Rapide reduced the file size from around 10.8 Mb each for the interior and exterior models to 4.5Mb each
