NACA 66 Special A/BGS

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.

   I looked at that picture inside the chassis, and my first thought was: "Damn, how many times would my head bounce off of the frame before I got it undercontrol when a spark went down the neck of my shirt". Hell of a welder, and great self control.

TIG welding (more modernly called "GTAW", and formerly referred to as "heliarc") isn't known for making a lot of sparks.  If
done right, it provides very delicate, precise control, and I tend to think of the process as "metal surgery".  The other welding
processes that do provide a lot of sparks are generally called "stick welding" or "MIG welding".
