Open all hatches. Extend all flaps and drag fins.

Wings, flaps, air speed, altitude pedals for the rudder.

I could use that for a leg, an arm, anything like that.

Well, there are other ways of making a flap.

We're going to learn how to make one flap.

If I make the flaps skinnier, I can use a bit less paper.

Well, if I unfold it and go back to the crease pattern, you can see that the upper left corner of that shape is the paper that went into the flap.

But we're going to start small.

This base has a lot of flaps in it.

Fold it in half, fold it in half, fold it again, until it gets long and narrow, and then we'll say at the end of that, that's a flap.

I can use it for something else.

And you can see there, it needs a quarter circle of paper to make a flap.

And if I make the flap from the middle, it uses a full circle.

So now we're ready to scale up.

I get to the limit of the minimum amount of paper needed.

There's other ways of making flaps.

Come in here.

There are other dimensions for flaps.

The wing has no steering controls, no flaps, no rudder.

If I put the flap on the edge, it uses a half circle of paper.

I'm way sure.

And from that stick figure, I somehow have to get to a folded shape that has a part for every bit of the subject, a flap for every leg.

But I have to say that there's older technologies that I tend to like.

This book is mine.

And thus we always get spirals of 5 and 8 on this flower, 5 and 8 on this artichoke, 5 and 8 on this pinecone.

These books are my books.
