Then it's on to a new distance record! JK, but seriously. Wish there were a way to improve aero on a drone.

I'm sure there is*, what do you have to work with?
I think the best use for tuft testing would be to put the car on a standard 100ft circle and hover the drone at the center in object tracking mode, zoomed to fill the frame. That way you get cross-wind performance on a short time scale.
For testing, it can orbit a waypoint, can it not? Put it on a 1000ft circle and count laps.
Hersbird — Motors (at least polyphase VFD) have a power curve that rises to a point where it flatlines due to back-EMF. Gears are only necessary so you can downsize the cabling for high-power low-RPMs situations.
edit: convert the props to a Prandtl-D airfoil.
