#2: Not at all what I had in mind, but I like it. The aircraft profile is decidedly a jet, which won't work. See the websites I list on the general comments for inspiration on the profile of a more typical experimental, propeller driven aircraft. Nice look.
I like both the RV and the Velocity a lot. I like that some of the more technical details of the airplanes are visible. One thing to watch out for, make sure that all lines are still clean when rasterized at 72dpi, 720x486. That's standard def TV 16:9.
