Wired Magazine published instructions for the paper airplane that just broke the Guinness World Record for duration of flight (time aloft).

I like the style. Very few steps, elegant technique, and very clever design. First, the locking mechanism for the fuselage was new to me. It’s a squash fold, which I’ve used for the same purpose, but he nails nose shut and creates smoother air flow.
Toda’s best trick isn’t obvious until you test fly the plane. No matter what angle the plane arrives at the apex of your throw, it rolls right side up and starts gliding. That’s brilliant.

Watch Toda’s record breaking throw:

Toda’s plane has less wing area than the previous record holder, which is a bit of a surprise. However, it’s higher aspect ratio wing may give it a glide ratio advantage. I never found Ken Blackburn’s plane to be outstanding in the glide slope arena. And frankly, I was never sure I’d ever folded it precisely the way Ken intended. With Toda’s plane, there’s no guess work.

The New Champ

Toda has not only re-written the record book. He’s re-defined how the winning duration plane should look and be constructed. He doesn’t load the nose with endless layers of paper, he spreads the layers tactically. The wings are wide and stiff. The leading edge is thin and clean. The center of gravity is lower. Absolutely no tape is needed (even though the rules allow a small piece). This is a really cool plane.
