and for extra credit, when the spoiler(lift dumper) opens on one side, have the other open also to allow crossflow, might be good to have it open out as well, so it negates the one sided drag (in the wrong direction) maybe. If it could open as a "scoop" on the upwind side then even better. I have them linked here, but testing would determine the best arrangement (i.e. windspeed vs AOA map) and pivot point, plus channeling to reduce crossflow delay.
