John, If the flaps being deployed caused a spinnaker effect wouldn't the wind be traveling fast enough to be flowing backwards across the wing thus making your glider drop from the sky like a rock. Flaps fully deployed should allow your glider to fly at it's slowest possible airspeed regardless of wind direction which is also the slowest possible ground speed for downwind landings.
