Weight build-up
WHEN FINISHING A MODEL, the weight to be added is often important in determining whether or not your project will be a successful flier. It is possible to ruin an otherwise sound project by a poor choice of finishing method. Weight is often cited as one of the principle reasons for selecting one method or material over another, but usually little consideration is given to the total added weight that comes from balsa preparation, the material, and priming. Often, it is not possible to make a wise choice of finishing method from available information. Instead, we rely upon our past experiences and the experiences of our RC colleagues. These hands-on observations are helpful, but they are not always accurate.
