'No Air' ?
they are Not in a Vacuum !
there is air, dense NON-moving air
no air moving underneath, means little to NO pressure differential
the air on top, coming over the raised front should provide down pressure
remembering my high school physics !

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 itโs 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 Iโll not worry about holding them down.

I have added a 2x8 PT triangle in front of the first panel so air cannot get under them although the front cap is 10โ higher than the roof...same height as the raised rails along each side of the roof.

I think I might build some kind of air foil/dam on the leading edge to keep air from getting underneath it at speed and creating lift.
