In this tutorial, we will be building a radio controlled model airplane using foam board. This RC Plane is easy to build and fly. It is also a good platform for beginners to learn about flying. You can also skip to check the build video tutorial of the RC plane by scrolling down this page.
For the novel, see Heartburn (novel) . Heartburn, also known as pyrosis, cardialgia, or acid indigestion, is a burning sensation in the chest, just behind the breastbone or in the epigastrium, the upper central abdomen. The pain often rises in the chest and may radiate to the neck, throat, or angle of the jaw.ymptoms of heartburn can be confused with the pain that is a symptom of an acute myocardial infarction and angina.
