When you put a gyroscope on an 300 kg aircraft
Ah yes this also happens when i try to make a motorcycle with gyroscope
This bug happens because the gyroscopes have very little mass and need to stabilize themselves too much. Since one rotational force attempts often create a discreperancy on the other, another rotational force acting on the other stands in to fix the discreperancy and the forces counteract, creating a dancing effect.
this made me laugh a bit
