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 is a burning pain in your chest, just behind your breastbone. The pain is often worse when lying down or bending over. Occasional heartburn is common and no cause for alarm. Most people can manage the discomfort of heartburn on their own with lifestyle changes and over-the-counter medications.
What causes heartburn during pregnancy? Heartburn occurs when the valve between the stomach and the esophagus are unable to prevent stomach acid from passing back into the esophagus. During pregnancy, the hormone progesterone causes the valve to relax, which can increase the frequency of heartburn. This allows stomach acid to pass into the esophagus and irritate the lining.
