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).
What Causes Heartburn? Heartburn typically occurs when contents from the stomach back up into the esophagus. The esophagus is a tube that carries food and fluids from the mouth into the stomach. Your esophagus connects to your stomach at a juncture known as the cardiac or lower esophageal sphincter.
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.
