Fat wings are an off shoot of the fun fly designs. They are not for 3D. The trend right now is thin. All the new 3D designs are going to thin wings. What the fat wings add is drag not lift. The overall design of the tango most likely will make it float fairly well dead stick, but most fat wing funflies dont glide all that well under dead stick conditions. If you dead sticked many of the early designed fat wing profiles, you better land it right where it was: because you were not going to get it back to the flight line. The added drag makes the plane not scoot across the sky. Funfly type planes are not fast. They are designed for funfly type maneuvers.

What does the fat wing do? It forces the plane to slow down due to the added drag. The 700 square inches of wing adds lift and makes it float. Remember it is all about wing loading.
