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 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. Some common foods that we eat and drink, stimulate increased stomach acid secretion setting the stage for heartburn.
