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.
Despite its name, heartburn has nothing to do with the heart (although some of the symptoms are similar to a heart attack). Heartburn is an irritation of the oesophagus caused by stomach contents, including stomach acid, that refluxes (comes up) from the stomach. Heartburn is also a symptom of more serious gastro-oesophageal reflux disease, or GORD. When swallowing, food passes down the throat and through the oesophagus to the stomach.
