slow plane

This plane was designed, apparently, on the 4th of January 1993. I don't believe a word of it, but it is quite recent. I've had to cheat the aerodynamics slightly, by my standards at least. However the result is a plane that flies in a wonderful trajectory either slowly or fast, which is quite rare. I would recommend this plane for those dull lectures, sitting on the back row, as it will fly very slowly right to the front to the amusment of fellow students.

Notes on the contruction

Standard beginning. A4 piece of paper folded down the middle, making creases at two corners.
Then fold as shown, creases so the marked edges join up well.
The same folds as several of my planes (nos 2 and 5), apart from the vertical one (on the diagram) is also a valley fold.
Fold one corner over, using the creases that are already there (marked in light grey). Be careful to keep the other folds whilst doing this, as it has a tendancy to move them.
Then fold the top flap under, along the center-line of the plane. I find this a lot easier if I make the fold by creases the entire plane in a mountain fold along this centre-line, then just folding the top flap under.
Do the same with the other half of the plane. First fold the entire flap over, along the crease line.
Again fold this flap under as in step 5. You can use the same method of before of folding the entire plane in half to make the crease first. However be careful that you do this accurately as you can easily get the problem that the two halves of the plane overlap in the middle, which makes the final step (of folding the plane in half to fly it) harder.
Now make the usual folds to get the wings and the flaps. I think that the fuselage should be around 2cm deep, and the flags should take up about half of the remaining wing width; in this case around 4.3cm. Now is the cheat that I try not to use. Make another fold to the upright flaps by folding the edges over, so that the pairs of lines meet up. This creates extra wings that are at an angle to the main wings. This gives the plane extra lift, without which it plummets into the ground. Make all these folds to be right-angles to create the plane.

Notes on throwing

Basically this plane is suited to flying slowly, as it doesn't really ever seem to stall, although it seems to respond very well to extra speed - but not by instantly hitting the ceiling. Again it will fly best if thrown straight and confidently.
