Yea, I'm not sure how it works, I think rotating bail of air. Just amazed that a simple piece of wood could lower drag.
Due to personal problems (2021 has been worse than 2020 for me), I am really limited on time to experiment with this, but I plan on doing more. I would like to see how a full cover would do.
I want to do some A-B runs on the interstate at 70+ MPH and with a 20 mile long loop. I also want to vary the length of the cover.
