I have translated from Japanese the specifications of the seduction freestyle wing airfoil.
i would really appreciate if some one could give me some explanations about wing airfoils, and in specific about this one.

''Main wing airfoil section originally symmetric . blade tip blade thickness 16% largest blade thickness position 20% , wing root blade thickness 13 5% largest blade thickness position 28. 5% Tail plane original symmetry , blade thickness 13% largest blade thickness position from 29% . center of gravity positioned 190mm of the main wing trailing edge ''

thank you
