Nice models! Good explosion as well. I've only done a little with the motion blur. Nothing that would work well with the apparent speed your flyers are going at. But, since it was a 30 sec animation, I didn't want to have to go and do 900 frames of post in Photoshop! It definatly added to the render time (54 hours!) but was worth it went it started off a conference and the audience applauded!
