You've gotten better at doing your camera shots and getting better angles. A few shots were too zoomed out to even tell what was going on. But that's easily correctable.
A couple of things you still need some help on are:
The low FPS of your videos. They're quite jerky and its because your computer isn't fast enough (at least its not fast enough to properly use Fraps). Try use the Save as AVI feature in the Film viewer. A few member who have slower/older computer are able to get high quality video because they use this feature rather than using Fraps. You may not notice it as much since your compiling all that video together, but to your audience it can really take away from the movie itself. If I'm going to buy a car and I have two choices. Both cars run fine but one is held together by duct tape, I'm gonna by the non-duct tape car.
I'd start working on a theme for your movies rather than just a collection of kill shots. You can make a movie out of flying in the MA, but maybe put a story behind it. Like your P39 movie. That at least had the basis of the movie of the 'awesomeness' of the P39.
