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.
Heartburn is a disease that occurs when gastric contents flow backward from the stomach into the esophagus. It is also termed reflux and gastroesophageal reflux disease (GERD) or pyrosis. Heartburn may or may not be associated with mucosal injury; that disease, termed esophagitis, is addressed in a separate article.
