Bill, as a pilot of over 45 years I even remember the B principle BUT there is a little more to how a wing create lift...angle of attack being very important and the high pressure created by/under it. Some people think lift is due solely to the camber of the wing...the B principle. Sorry but it’s not that simple. A cambered wing only increases the differences in pressure that create lift...with no high pressure under the panels, there will be very little lift. The most important item for lift is the angle of attack of the wing...the panels probably have a negative angle of attack once the air off the front front finally comes back down.
I will put small pieces of paper between the supports and the roof. If they are still there after a short high speed run I’ll not worry about holding them down.
