Leading and trailing edges

Make them straight, light and strong

Because so many people are getting started in the hobby by flying almost-ready-to-fly (ARF) models, they are learning basic model-building skills much later in the process of becoming pilots-usually, when their ARFs require repair! Learning how to make proper model structures is an important step toward building and flying more advanced and specialized airplanes. Strong wings are perhaps the most important part of a model's structure; along with the main spar, the leading and trailing edges (LEs and TEs) add much to the wing's strength. Making these smooth and fair also contributes to the model's aerodynamic efficiency. Here are some basic tips for building straight and true LEs and TEs.
