does a twin engine lose its gyroscopic properties of inertia?

Nothing disappears, nothing wrong. You get to look into what's happening in a gyro more in details. Don't see any question really.

my point is pretty clear in this drawing:


take the mass of the wizard neglectable(what brings down your point) compared with the propellers
