I was wondering if it makes any difference if the mass is balanced above or below the point of thrust. See image below for clarification:
In the image you can see two configurations. The red arrow / point in both represents the force / location pushing against the mass (hull of craft). This force can be an impulse or prolonged force. the blue arrows in both represent the upwards force of the rotors. And the green arrow represents the gravity in both.
I would imagine that balancing (keep the craft hovering) would be easier with the mass below the rotors since then gravity helps pulling the center of mass back under the center of the rotors. While if the center of gravity would be above the rotors and it would be pushed to an offset gravity would help make this offset worse.
So does it makes any difference for the stability of the mass (center of gravity) is above or below the point of thrust?
just to be sure config A represents the mass and center of gravity being above the point of trust, and in config B it is below the point of trust.
I am have no engineering or physics background so please explain this as simple to me if possible :)
Let me know if this is not the right place to ask and maybe suggest me where to ask this then.
