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 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.
