I did talk to Rob about their thinking for a control idea for their flap control. They set the flap(s) initially to provide 3000 lbs of down force at 180-200 mph . They have calculated what the flap angle has to be at increased speeds to maintain the 3000 lb of down force and the flap angle is then reduced based upon their speed. I think that it is somewhat a hybrid system that uses driver input and a control that sets the flaps. As I remember the flaps are actuated by an electrically driven screw jack. My guess is that if you contacted Rob's partner Brandon Barnard he could be of great help. Great guy just like Rob.
