Ah ok...well that's interesting, then.
By pure intuition, i'd say that they energize the flow over the pods to keep it nicely attached, thus creating lift. However this lift would be compensated by the rear wing complex, which would receive a "better" airflow (=cleaner streams, greater angulation-->greater AoA,...). Is this the way they work? Let's find out...
I'll test them on my model as soon as i get the time.
