BUILD A PULL-STRING HELICOPTER AND LAUNCHER

This project is under construction but will be ready soon. You can see the rough first draft of the introduction and instructional video here http://video.google.com/videoplay?docid=7621320534835658334&hl=en There will be changes, and I'm still redesigning the launcher, so there is no video of launcher construction.

Here are some still pictures from the introduction and instructions.

   

Check back the final version of the instructions.
