Use these controls to define the vessel's angular velocity around its three principal axes. You can adjust the velocity of rotation around the x-axis (pitch), y-axis (yaw) and z-axis (bank).
To terminate spin altogether, press the Kill button.
Note that the angular velocity components can oscillate between the three axes, depending on the vessel's principal moments of inertia (PMI). This means that pressing the Refresh button repeatedly may change the angular velocity values in the three axes, even if no additional torque is applied.
Likewise, pressing the Apply button repeatedly with the same angular velocity values can lead to abrupt changes in the vessel spin.
The angular velocity settings have no effect for vessels on the ground.
