I'm sure I'm not the only one who view these 'aero' templates to be very narrow in their scope. The almost '2D' shapes are almost always tested and highly scrutinized with just straight head winds. Pragmatic 'optimal' forms will surely change when these shapes are evaluated with off-center cross winds. The relatively high & flat sides of some of these shapes will go through erratic yaw movements and have straight line instability. Wind tunnel researchers/junkies & especially HPV designers are always mindful of constantly changing cross winds' effect on their designs. I'd like to see wind tunnel smoke trails, tuft testing or CFD flow visualization art created by off-center sidewinds.
