Thanks for the tips. I have the "shooting airshows in manual" thread bookmarked, but I'll try your suggestions first. Now...I just need an airshow. There used to be one every year in Westminster and Frederick, but it's been a long time since they had one (at least in Westminster).
Last year I got excited when I saw "Wings of Freedom" flyers around town. That was the name of the airshow that came to Westminster. But it wasn't an air show this time. There were 3 static displays (B-17, B-24, and a P-51). They only flew when someone dropped $400 for a 20 or 30 minute ride.
