Introduction: Hybrid Rocket Engine Model
I have chosen to remove the contents of this instructable as I no longer consider projects like this to be safe and informative.
A real rocket engine requires components that are not easily purchased or manufactured at home. The materials used for this project are not recommended for use in any high-temperature environment.
Please use caution, safety, and common sense when working with rockets. Do not attempt to build your own engine unless you have appropriate training and experience.
