Have you doped it yet? my Avenger looked the same way until I started applying the dope then it shrunk in . The poly span itself doesnt shrink enough to draw it between the ribs. and as stated, it probably makes it a better airfoil without the shrinking down, but it sure looks cool,
THOUGH some argument could be made for a reduction in spanwise flow of air across the wing with the Ibeam style scalloping between the ribs
