EMDevices, Get a real gyro and play with it. You'll see there is no fraud in that video if you have played around with a fast spinning gyroscope. You can easily have a gyro attached to a string at one end when spinning and it will stay horizontal as long as it's spinning fast while only being held by the string at one end with nothing to support the other end.
Yes there is no fraud. And I am almost convinced that the "Laithwaite effect" is the same gyro effect that you show us, but inverted. A gyro having a horizontal axle whose the end is placed on a pivot, turns around due to precession, as on your picture. This happens only if the gyro is submitted to a vertical force (gravity) that exerts a torque in a vertical plane onto the gyro axle. Inversely the action of forcing a rotation similar to the precession, exerts a torque onto the gyro axle, and so, it goes up or down depending on the rotation direction. To clearly show this effect, I have attached the end of the offset arm of my gyro to a flexible piece that is fastened to a ball bearing having a vertical axis secured to a heavy base (around 7Kg). The horizontal rotation can last much more time that the gyro rotation. Depending on the clockwise or anticlockwise direction of the rotation launched by hand, the gyro flies up or down and maintains its altitude during several turns before slowing. It seems that there is no change of weight. Although I have weighted my system, I can't confirm this point 100% because my weighing machine was not very sensitive (0.1 Kg). Imho we have not a vertical force acting onto the gyro, but a torque, and consequently the gyro weight is transfered to the pivot point which in the Faithwaite's experiment, is his hand. I'm almost convinced that his hand supports all the weight, but the torque that tends to raise the gyro compensates the ordinary torque caused by a weight at the end of a long arm, and consequently his hand can hold the ensemble because the force is now vertical and doesn't twist his wrist.
