The Spyder (Paper Aeroplane)


 

Spyder paper aeroplanes are beautiful to look at. They can also fly pretty well. Although you're unlikely to break any records with this design, if they're well made, you can get some decent 10-15 metre flights out of them.

The Spyder is also a good paper aeroplane for performing aerodynamic experiments, as it has a front set of wings (called canards), as well as a back set. You can experiment with tweaking this wings indepedently to see what different effects they have on the paper aeroplane's flight pattern.


1. Take one A4 piece of paper.




2. Fold the piece of paper exactly in half longways, then unfold. You will use the crease you have created as a guide line in future steps.




3. Fold the corners at one end of the paper so they meet the centre line.




4. Fold the tip of the plane back so it meets the points where the other folds cross.




5. Now refold along the centre line, so that the folds you have made in steps 2-4 are on the outside.




6. Fold along the yellow line on one side of the paper as shown in the diagram on the left. You should get something that looks like the diagram on the right.




7. Repeat the fold on the other side.




8. Fold along the yellow line on one side of the paper. If you've got a ruler handy, use the dimensions as shown in the diagram. If not, just use your best guess. You should aim for something that looks like the diagram on the right.




9. Repeat the fold on the other side.


10. Now fold up along the yellow line on one side of the paper. It is possible to fold the entire length of paper in one go; however, sometimes it is easy to do it in two stages, as show by the marks A and B in the diagram.





11. Repeat the fold on the other side.




12. Uncrease along the centre line so the plane is flat.




13. Fold inwards along the yellow lines.




14. Refold along the centre line, so that the folds you made in Step 13 are on the inside.




15. Now we're going to fold down both the front and back wings on one side of the plane. It's possible to fold both at once, but you can also do one at a time.




16. Repeat the fold(s) on the other side. You should end up with something that looks like this.




17. Flip the paper aeroplane on to its back. It's now time to fold the fins.




18. Flip the plane back over and behold! You're done! Tell your friends. But do not celebrate too hard, lest you forget that almost all paper aeroplanes need to be calibrated before they fly properly. Click here now for instructions on what to do!
