Ahhh, now consider this...

Is it strong enough to rotate a Zero lb fuse? Because that is essentially what you are rotating... 2.5 lbs forward of the nacelles, and 2.5 lbs aft.

As long as you're doing tests, try this... Balance a fuselage on something like the back of a chair. Now see how much force it takes to push the nose or tail down.

Oh, and add one more thing to the equation...
A vertical lift aircraft, while in hover, generates a high-pressure "bubble" of air directly underneath itself. And until a sufficient altitude is reached, the craft wants to "fall off the bubble". Think of it as you, standing on a 5 foot diameter ball in a swimming pool. Just ask the Heli guys. They will tell you all about the bubble.
