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.
The symptoms of heartburn are a tight, painful feeling through your chest. Heartburn is caused by acid reflux, which happens when stomach acid is released into the esophagus. The stomach acid eats away at the lining of the esophagus and can cause lasting damage. If you experience frequent heartburn, you may have a condition called acid reflux disease, or gastroesophageal reflux disease (GERD). Lifestyle and overall health are important factors in heartburn symptoms.
