In a double gimbal system, how many planes allow free motion around the gyro?

Explanation:
Two planes. A double gimbal system provides two independent axes of rotation, each offering tilt in a different plane. This lets the gyro’s spin axis tilt freely in two perpendicular directions, giving motion in two distinct planes around the rotor. With one gimbal you’d have only one plane of motion, and with more than two gimbals you’d gain additional planes, but a typical double gimbal yields two.
