Horizontal Stabilizer Size for a stable flight
Pitch Picture
Fuselage
A nose dive is shown in this picture where the center of gravity is shown balancing on a finger
Horizontal Stabilizer Size for an unstable flight
Horizontal Stabilizer Tradeoff
A straight flight is shown in this picture where the center of gravity is shown balancing on a finger
The center of gravity has a wing chord (width) of this for a straight flight
Stabilizer
The center of gravity has a wing chord (width) of this for a nose dive
Horizontal Stabilizer controls this
Roll Picture
Center of Gravity
Horizontal Stabilizer Size for a upward pitch
Yaw Picture
Too much upward lift in this picture where the center of gravity is shown balancing on a finger
The center of gravity has a wing chord (width) of this for a pop up
Ballast
Horizontal stabilizer does NOT control this
A larger horizontal stabilizer catches air to prevent yaw & roll, but too large causes the center of gravity to shift to the tail.
Pitch and roll
Yaw
Point at which a glider rotates around. The balance point of the glider.
