-
Dihedral Angle
Dihedral, the upward angle of the wings from the fuselage, contributes significantly to lateral stability. When the aircraft encounters a disturbance that causes it to roll, the lowered wing generates more lift due to its increased angle of attack. This differential lift creates a restoring moment, counteracting the roll and returning the aircraft to a level attitude. A sky surfer RC plane with sufficient dihedral will exhibit a self-correcting tendency, minimizing the need for constant pilot input and promoting smoother, more stable flight, especially in turbulent conditions. The presence of excessive dihedral, however, can reduce responsiveness and make coordinated turns more challenging.
-
Center of Gravity (CG) Location
The position of the center of gravity (CG) is critical for longitudinal stability. An appropriately positioned CG, typically slightly forward of the wing’s center of lift, creates a stable equilibrium. If the aircraft is pitched up or down, the resulting aerodynamic forces will generate a restoring moment, returning the aircraft to its original pitch attitude. A CG that is too far forward will result in excessive stability, making the aircraft difficult to maneuver. Conversely, a CG that is too far aft will render the aircraft unstable and prone to erratic behavior. Precise CG placement, as specified in the aircraft’s documentation, is essential for achieving optimal stability and control.
