Have you done the experiment? "Syd12107" has claimed to in this thread: http://www.physicsforums.com/archive/index.php/t-173215.html http://www.physicsforums.com/archive/index.php/t-173215.html The result was that counter rotating gyroscopes had no net effect. The only thing that matters is total angular momentum. The resistance to being tilted is a _secondary_ effect. The push gets translated into motion at right angles to the push, and this motion gets translated into push at one more right-angle, exactly countering the original push. For two counter-rotating gyroscopes, this first-stage motion of one is exactly countered by the other, leading to no net effect. Really, truly.
