Oh, it was known..the Equalizer had a stunt-type airfoil and a big wing for the time (390 sq. in. if I recall right...maybe it was 360)...seems like it was a Nietzband design, not sure now. It was slower than typical, maybe as much as 5 mph, but could turn inside (and quicker than) anyone. It was one of my favorite airplanes to fly, even though my home designs tended more toward the small-but-really-fast types, like most everyone else was flying.
