The first one is the easiest to make, it only requires just sheet of paper and a paper clip. It works better if the paper clip is heavy in relation to the paper and the paper is thick compared to its size.
To build it, just fold two edges of the paper up and fix the paper clip in the middle of the nose.
It shouldn't be thrown hard. You'll have to experiment to get the right, if the paper is too large for the clip it will become unstable as it slows down and tip nose up, if it's too wide it'll be directionally unstable.
The second one requires scissors and tape to built. It too will work well in small sizes for indoor use.
First build the fuselage by folding a piece of paper four times and taping the outer parts to each other forming a straight, hollow, triangular fuselage.
To build the wings fold a piece of paper over, with the part which will become the upper surface a bit larger. Then pull the rear edge of the undersurface a little bit towards the rear edge of the upper surface, it doesn't have to and shouldn't meet the edge. Tape it in position, forming a curved airfoil shape.
The curvature on the smaller, both in span and chord, canard should be slightly larger than for the rear main wing.
Tape the wings to each end of the fuselage, they can extend over the edges of it.
The vertical stabilizers are a piece of paper folded in a V and taped to the fuselage just in front of the main wing.
Note: When you fold paper and have trouble getting straight folds, this may be because you're folding across the fibres in the paper. Rotate the paper 90 degress and try again, if it works better that way, do it that way and cut the paper to fit the new direction.
I put up the original web page on them nearly ten years ago.)
