Here's my take on 1/64th scale aerodynamics...Yes, while the resistance of static air on a body in motion is a factor on any scale, it will become less influential when the average frontal area is already pretty small(eg. 1/64th). Also, consider the fact that real world benefits of maximized aerodynamic designs are typically evident over long distances/periods of time. That said, I do factor in obvious positive aero qualities/frontal area when I'm qualifying potential entries. Of coarse, roll-ability and track-ability are still "king", but I have opted for minimal frontal area when all other factors have been equal, especially when racing on long(40ft+) courses.
