We would like to know if we need to make a custom head or if there is an existing head that we could adapt for this use. I would also like to hear tips and suggestions on other things we can do to improve our mileage. We have the carbon fiber aerodynamic body under control, but would like to hear other ways of improving efficiency.

Are there any rules limiting what you can do?
