I think you're talking about a totally different thing. For a controller to be well balanced, the center of gravity needs to be at about the center of the hand placement when holding the controller. Move that balance point forward, and it wants to fall out of your hand, forcing you to flex your hand to keep it from falling. That causes fatigue, and hinders fine motor movement in your fingers... which is how you fly precisely.
yes, that design can sit on a table, but thats with a controller attached, and only with a long metal piece that sticks out from the back of the controller inches past the back of the antenna. The reason thats there, is because its unbalanced, and needs a huge footprint to stay upright.
Look to the right of the picture, you'll see what I mean.
I dont know if I'm explaining well, so here's a video. Hope this helps.
