The incidence and the thrust line from the side view is at 0 degrees as per the plans. Now what should I do, time I set the wing incidence I leveled the fuselage with help of Robart Incidence meter. Keeping it in between the F1 and F 2 former.

Now what exactlly should be the problem the thrust of the engine or the incidence?......

Also like to no let say its a Incidence problem and I give a 1 degree down thrust on the engine, will it be right to do? Kindly let me know how to solve the problem.
