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 a very common digestive problem linked to acid reflux, a condition where stomach acid and other contents flow backward from the stomach into the esophagus. This causes heartburn symptoms like burning sensations, chest pain, a sour taste in the mouth, and sometimes coughing or gassiness. Risk factors and causes of heartburn include eating a poor diet, obesity, a sedentary lifestyle, older age and high levels of inflammation.
