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 basic cause of heartburn is a lower esophageal sphincter, or LES, that doesn't tighten as it should. Two excesses often contribute to this problem: too much food in the stomach (overeating) or too much pressure on the stomach (frequently from obesity, pregnancy, or constipation).ome of the symptoms, however, are similar to those of a heart attack or heart disease. Heartburn is an irritation of the esophagus that is caused by stomach acid.
