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
Yaw Picture
Stabilizer
Horizontal Stabilizer controls this
Horizontal Stabilizer Size for a upward pitch
Horizontal Stabilizer Size for a stable flight
Horizontal stabilizer does NOT control this
A nose dive is shown in this picture where the center of gravity is shown balancing on a finger
Roll Picture
A larger horizontal stabilizer catches air to prevent yaw & roll, but too large causes the center of gravity to shift to the tail.
