Yes, the planes are rigged identical.Rigging theSE5 at(-3,+2,+1), or (0,+5,+4) or even (-4,+1, 0) is doing the same thing to the plane. The only difference is that the Datum Line that the numbers are referenced to has inclined in angle. The airplane doesn't care. But notice that in all of the examples that the angle between the prop thrustline and stab is 4 degrees. That number will determine the dynamic balance of the fuselage regardless of where the wing is set.</p>

An example. If we take a 10 pound iron bar and tie a stringat the exact center and hang it by the other end of the stringto the ceiling we can closely model an airplane fuselage. The string tied to the ceiling represents the wings lift. If you lightly touch one end of the bar it will rotate in pitch about the center where the string is attached. This is exactly what an airplane fuselage does in flight. The only difference is that the engine and tail group are different weights so the "string" has to be tied to the fuselage with a forward bias to accomodate the heavy motor. Visualizing this heavy bar on a string idea is critical to understanding dynamic balance.</p>

In your SE5 example (-4, +1, 0) the wing (+1) is just along for the ride. The number that the plane cares about is (-4, ,0). If we make the runway on the surface of the earth our Datum Line thefuselage pitchin level flight will be a balance between the downward force at the nose of the plane and thelift force at the tail (could be + or -). At 3/4 throttle, level flight might be (-2, ,+2) but full throttlethe plane now flies at (-5, ,-1). The -4 degree difference between thrust and stab of your SE5 waschosen based onengine powerand stab liftso that the plane would pitch forward just enough to maintain level flight as airspeed increased.</p>

So now if we look at the SE5 (-4,+1, 0) we can see that changing it to (-4, 0, 0) doesn't decrease the downthrust 1 degree, it decreases the wing incidence by 1 degree at all airspeeds because the difference between thrust angle and stab is still 4 degrees. Alternatively, changing it to (-3, +1, 0) is a 1 degree reduction in downthrust because the difference between thrust and stab is now 3 degrees. The reason for this is that the Y component of the thrust is reduced but the tails ability to generate lift at different angles of attack has not been.
