    ## Motor Test Stand # Motor Test Stand
    In order to verify the motor characteristics and choose the correct motors for a project, a motor test stand shall be designed to measure these characteristics and other data associated with a model rocket motor. The test stand shall be able to test standard size motors (18 mm diameter) but also larger motors in the future. It shall be able to measure thrust and ejection forces over time. The motor shall be electrically started and the data shall be recorded with an adequate measurement rate.
