Nice diagrams. Do you know the book "Kids' Shenanigans" by Klutz? [1] I grew up with it, and it has three paper airplane designs, corresponding to your "Basic Dart", your "The Square Plane", and one called the "Nakamura Lock"[2] (also mentioned elsewhere in this thread), which you don't seem to have but bears some resemblance to your "Tail Spin".
