Default EDF Mounting Incidence and Toe out?

Hi,

I am trying to design a twin EDF aircraft (with two rear fuselage mounted 110mm fans) and going by the 3 views the engines will need 2.7 degree positive incidence (up), and also 1 degree toe out (rotated outboard at the front).

Can anyone tell me the implications of this setup?

Obviously the positive incidence will result in a nose down moment, however the stab is mounted at a negative angle of attack so this should countetact that moment somewhat (by providing a nose up moment).

I have no idea what the toe out would do to the aircraft. I would assume the engines may "fight" against each other?

Thanks!
