Adjust the paper helicopter template parameters by specifying factor levels, fill in the design matrix, and generate the PDF file with the templates in different sizes, built according to your own measurements.
*Note: This PDF contains two distinct paper helicopter templates: one with all '-' factor levels, and the other with all '+' factor levels, respectively. These templates are provided for illustrative purposes only and cannot be used in a paper helicopter experiment that adheres to the default values given in Table 1 - these templates were built using different values for the parameters and factor levels, see the cover page in the PDF file.
