I hate to pose a question that so nakedly exposes my ignorance of aerodynamic basics, but we have a problem with a B-17:

On a single engine plane with wing and stabilizer incidence set at 0 degrees, putting 2 degree down incidence on the engine will cause the whole plane to go down, correct?

On a similar plane with multiple engines (wing-mounted), what happens if the engines are given a down incidence of 2 degrees?

Will the plane still go down?

Or does the engine thrust line force the wing and stab into relative 2 degree positive position in flight and cause the plane to go up?

Or does it depend on the plane? B-17?

Thank You
