A slight clarification here... The APR wing was designed/specified for use in World Challenge TC. Before I bought one a couple summers ago, I had them measure the thing in the shop to find out it was 1/4" too big in the center, but the chord is only 6.5" or so on the sides. Overall it fits within the area spec'd for an 8.5" x 48" wing, so I (and a couple others) wrote letters to clarify its legality in STU.
Mounting brackets and endplates are a different story, but the wing itself is legal.
Regarding the height below the roofline, I thought the rule was the high point of the wing- not the endplates- was the measurement point ???
