In those two areas the blades are passing each other in the opposite direction so while the blades are all spinning in the same direction when they pass each other the air flows are in the oppsite direction. The baffles help in limiting the size of this area to limit the turbulance. Blade placement also comes into play, too high and it can over pressure the deck and too low can cause too much air to escape under the baffle.
so what happens when the deck is over pressureized? i took one spacer out yesterday and it greatly reduced blowout, thinking one more might do the trick to eliminate it
