Another amazing work by NXTLiftBoy - a paper plane shooter, made from a single NXT set.
You can find link to builiding instructions and some additional details here. Follow the instructions below from NXTLiftBoy:

Here is an update for NXTPlaneShooter:
I made pictures while taking it apart.
You can find these “build instructions” on PhotoBucket.
I uploaded the pictures in batches of 100, and the order got corrupted again
Make sure you follow the picture numbers in reverse! The first picture to look at is named IMG_2546.JPG, the next has number 2545 and so on downto until 2167, which is the last picture.
It seems to jump every batch, so at each xx66 you need to jump and locate xx65.
You can verify the number of a picture by hovering the mouse over it and reading the status bar of your browser (enable it in your view if need be).

To find the proper building order do like this:
1 follow the link above to the album,
2 click “View All” and be patient to load all 380 shots in one page…
3 scroll 80 pictures down until the one with the green batteries in the brick, here it starts!
4 build up- and backwards the first set of 80 pictures,
5 jump from 2467 to 2466, located 80+100 pictures down now, 2466 is just next to the big gear wheel,
6 build back 100 pictures to 2367, just until the battery box again,
7 jump from 2367 to 2366, located 100+100 pictures down now,
and repeat steps 6 and 7 twice, offsetting the numbers by 100 every time, so you took all 380 simple steps to build this beast…:)

You need to be aware that the NXTPlaneShooter requires manual operation, or you can write your own program for it in the LEGO visual programming language (NXT-G). Take care not to snap the ropes!

The paper plane has a staple in the front, ensuring that the plane moves along with the accelerating grey pin, otherwise the paper may just glide through the slit in the grey pin.

Happy shooting,
