Hello, Is the above book by David Sleeter any good? I am interested in making some of my own small rocket motors. Will this book be a good start to what I need? It says that many engines can be made with common everyday stuff. How easy are these ingredients to get (bearing in mind, I live in Canada). They have long since removed Salt peter (Potassium nitrate) and sulphur from the corner drug stores. I used to make gun powder as a kid, but can't find the ingredients around any more.
Thanks everyone Richard
