>>1077863well, the problem is more complicated than that.
there is indeed a rolling moment, but its center of application is all wrong.
Usually the rolling moment is supplied by the ailerons and coincides with the wing. However, here there is a more significant twisting moment imparted to the wing by the ascending and descending elevators, located at the end of a long moment arm (the booms).
Even if the twisting itself wont rip the wing apart, the assymetrical aerodynamic loading appearing as a result of the uneven airfoil deformation surely will.
