Great idea for a video series!
My initial suggestion, in this era of shortened attention spans, is on episode length.
I'm only partway through one (surprise: I chose the shortest one to view first... then again, that's because I should be working
) and it's fantastically info dense! If your goal is a seminar-type program (and I suspect it is), that's fantastic. But if your goal is widest viewership, it may be a drawback.
But now I know what I'll be doing for another couple of hours in the near future.
Obvious suggestion (if it hasn't been made yet): examination of some DIY drag-reduction mods, as found throughout our aero subforum.
Also: welcome to the forum!
