INTRODUCTION: The gyrostatic precession effect is a very interesting effect to study. As the gyroscope begins to rotate in a counter-clockwise direction and you gently rotate the platform, the gyroscope (motor/rotor) assembly moves upward very rapidly. When the gyroscope begins to rotate in a clockwise direction and you gently rotate the platform in the same direction, the gyroscope assembly moves downward very rapidly.

CONCLUSION: Close examination of the first four videos (VIDEO #1 thru #4) above shows that a very interesting phenomenon occurs when the rotor (gyroscope) is spun up to speed. The motor/rotor assembly tips at approximately a 45 degree angle either up or down, which is dependent upon how the rotor side is weighted. In other words, if the rotor side is weighted slightly heavy, the motor/rotor assembly tips down as the rotor is brought up to speed. However, if the rotor side is weighted light, the motor/rotor assembly tips up as the rotor is brought up to speed.

The last two videos (VIDEO #5 and #6) above shows what happens when the rotor is brought up to speed and the platform is rotated, an equilibrium is reached between the angle of motor/rotor assembly, spin of the rotor, and the rotation speed of the platform. The mass of the various parts also plays a part. I observed an angle of approximately 45 degrees.
