Assembling the Airplane. Once we have the Wing and Power Pod ready, we go ahead and glue them together as in Fig 3.1. Then, we install the control horn on the elevator and run a control rod from the servo to the elevatorâs control horn as in Fig 3.2. We follow the same step for the rudder (Fig 3.3).
Heartburn Causes. Heartburn is actually a symptom of GERD (gastroesophageal reflux disease), and is caused by acid refluxing back into the esophagus. Risk factors include those that increase the production of acid in the stomach, as well as structural problems that allow acid reflux into the esophagus.
Despite its name, heartburn has nothing to do with the heart. Some of the symptoms, however, are similar to those of a heart attack or heart disease. Heartburn is an irritation of the esophagus that is caused by stomach acid. This can create a burning discomfort in the upper abdomen or below the breast bone.
