I made a couple of videos if you are interested in watching. The first is a slide show and about 12 minutes of the car being built and what I did along the way. The second is the one to watch if you don't have much time. It is of the car being fired off for almost the first time. It sounds very nice to me.http://www.youtube.com/watch?v=f02VfBJ2mushttp://www.youtube.com/watch?v=QjNBirXq5S0
