If it's a fly-by wire system, you may be able to avoid twisting stress by varying the angles of the elevators on each tail so that you add force to oppose that twist. Also, I don't think it's expected to undertake any really drastic maneuvers. You'd fly it in decent weather on a relatively short ascent, and use a very gently take-off and landing profile.
