Like everyone here I tried the free version then bought the full version of FRAPS. Great for screen shots as well, no more changing png to jpg.
Well worth the money if you intend to make short movies.

all over the place at times and my gunnery
I could do a IL2 film but with the auto pilot on and thats cheating. I will stick to CF3 where I got better control.
