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.

Here are some 1/64th scale wind tunnel test videos that are a few years old. I'm not familiar with the creator but the videos are well made showing multiple angles.

The CUL8R is one my favorite fantasy castings for racing. It has an efficient wedge shape with no rear spoiler/wing in obscure air flow. It also has a unique arched chassis that I suspected might help alleviate pressure underneath the car. This video shows exactly that. The dense white smoke (indicating higher pressure) is visible beneath the chassis and it steadily exits in front of the rear wheels in the video.
