Given the above summary, write a detailed text in English for it.
For your paper airplane to soar true, it’s important that you use a piece of paper that is neither too light nor too heavy. In most cases, a standard sheet of 8.5”x11” (A4) letter paper will be the perfect size, weight and thickness to make a plane that when folded correctly will fly for dozens of feet. The flimsiness of thin papers like newsprint keeps them from catching the air, while cardstock, construction paper and other heavier types of paper will create too much drag, and will also be more difficult to fold. You are not just limited to paper, cardboard if cut through the center could be used if needed.    The types of paper commonly used in offices—crisp, smooth and perfectly weighted—often make for excellent paper planes. It’s okay to use thinner paper for smaller planes, since the compact size will compensate for the weight difference. Likewise, heavier paper can be used to make oversized planes. Until you’ve mastered the folding technique, avoid working with papers with unusual dimensions. Most paper airplane folding instructions are given with 8.5”x11” (A4) paper in mind. Altering the height or width of the paper can drastically change how the airplane turns out, and if it’s too wide or too narrow, it may not fly at all. If you’re working with scrap paper, cut or tear it until it’s roughly the proportions of letter paper, then reproduce the folds on a slightly larger or smaller scale.
