Control surface

adjusting the reaction to the different axises

A control surface is an aerodynamic part that provides reactive force when in motion relative to the surrounding atmosphere. Control surfaces provide greater control and stability to rockets and aircraft, though they are of no use outside of an atmosphere.

Each of the control surfaces is tweakable in the game - can be adjusted by the axises. It can prevent the craft from the overreactions, gives better control by ensuring "free" control surface for the given axises. These can be set off in the SPH or VAB, and even after the launch of the craft.

The state of the control surfaces' (and its symmetrical pairs) reaction to the control of the axises can be adjusted by the buttons next to the names of the axises in a popping up window by right clicking ion the selected control surface.

• Pitch : lits and lowers the nose of the craft and can be controlled with a horizontal control surfaces far from the center of mass.
• Yaw : turns the craft left and right. It can be controlled most efficiently with vertical control surfaces far from the center of mass.
• Roll : rolls the craft around the longitudinal axis of the craft, can be controlled most efficiently with symmetrical control surfaces far from the longitudinal axis (like at the end of the wings).

The Active/Inactive label by the axis indicates the relation of the control surface to the given axis.

(As the KSP aerodynamic model is not very realistic now (0.25^[outdated]), the crafts can be controlled quite "well" without adjusting too)
