For a motor there is two types, a core burner and an end burner. A core burner has a hollow core and if the core’s length is two short then it may not be successful and if it is too long then the chambers pressure may exceed and cato. A end burner is easier to manufacture due to the way it is designed. Ender Burners have a faster burn time and are a full packed motor. This type of motor produces a constant level of thrust. The down side to end burners is that they have a chance exploding because the casing inside is unprotected from the flame. There are two types of motor fuels that we had the option to choose: Potassium nitrate and Black powder. Black powder burns fast and can exert a lot of thrust. Black powder can help reach a high altitude really quickly. A potassium nitrate motor or sugar motor burns slower in comparsion to a black powder motor.
