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, also known as acid indigestion, is a burning sensation in the central chest or upper central abdomen. The pain often rises in the chest and may radiate to the neck, throat, or angle of the jaw. Heartburn is usually due to regurgitation of gastric acid into the esophagus and is the major symptom of gastroesophageal reflux disease. In about 0.6% of cases it is a symptom of ischemic heart disease.
