Why do you add sulphur? Presumably you know that making a rocket from sodium chlorate and sugar alone is a very bad idea already, but adding sulphur makes things twice as bad.
You should spend a significant amount of time reading every piece of quality information on the subject you can find and afford before you start making fireworks, and should be experienced in handling tamer compositions such as black powder before moving onto chlorate comps (which are really limited to stars/coloured fires and burst charges - NOT rockets).
Please, if you must experiment without reading the proper material first, take my word for it, the composition and usage you describe will lead to an accident. Potassium nitrate is very easy to get, at a price, and some searching will turn up several very cheap sources too. Potassium nitrate propellants are much, much safer to make, handle and store. They are also significantly cheaper, and in practice will give much better, more consistant rockets.
Finally, try not to be put off by this response. If you are unsure as to the safety of a procedure, and are unable to find reliable answers from existing sources, then please do ask on the forum. Any of us would be willing to answer an obvious question if it's going to stop someone from getting hurt.
