I've never seen the plans for the Tiger Tail but if it builds up similar to any other foam winged plane, the sheeting will be glued down first and trimmed even with the leading edge and trailing edge. Flat balsa pieces are then glued to the leading and trailing edges and shaped to form the rest of the airfoil.

I've done one giant scale plane that had formed balsa leading edges and it was NOT fun to do. I had to make two seperate jigs in order to form the wood.
