This propulsion system has been tested to go up to 91KM an hour.

As a request of a friend, I am uploading these kinds of files because they think I should before people steal my ideas..... I don`t mind though.

The file has "copy of" because I wanted to keep my original, but still change the filename to: 91 KM Propulsion system.phn, because phunbox didn`t accept my error when I saved it with a . at the end (system..phn).
