Yes, the planes are rigged identical.  Rigging the SE5 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.

An example.  If we take a 10 pound iron bar and tie a string at the exact center and hang it by the other end of the string to 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.

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 the fuselage pitch in level flight will be a balance between the downward force at the nose of the plane and the lift force at the tail (could be + or -).  At 3/4 throttle, level flight might be (-2,  ,+2) but full throttle the plane now flies at (-5,  ,-1).  The -4 degree difference between thrust and stab of your SE5 was chosen based on engine power and stab lift so that the plane would pitch forward just enough to maintain level flight as airspeed increased.

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.

PS: Welcome to RCU 1texasgolfer.  I think you'll like it here.

Interesting how different people view the  use of referrence lines 

 On the latest superlight electric aerobats  (rc types of  400 sq inches ) the  entire model is simply laid out  0-0-0

 why?

 because amodel this  size may  weigh -ready to fly - 6 ounces (not a misprint) and have  thrust of 18 ounces  (not a misprint.)

 with these  relationships  ,the  angles of attackneeded  are  extremely small  for  even fairly sharp maneuveing

 fo r th  wild n wooly flailing

 the model can actually turn in it's own length  with litle or no noticable  loss of  altitude

We can't post videos here (thank goodness) but there are a number of  videos of models which do this  very easily and smoothly.

 here is one which is quite  revealing.

 Tho this type flying may seem preposterous to some - the  technical  advances which have made it possible  are  very interesting
Better yet , by  adapting the  methods learned , many new  RPV (pilotless craft) can do things totally impossible  with piloted vehicles
 In models   we have  adapted eight to power  and wingloadings,  totally  removed from those when we first flew RC in 1970
 much of the  data considered necessary  then , is  simply not needed  for  this apprach . stalling-, 
 banking required for  turns-  take off  minimum speeds -,  etc., are not relevant 
 the model  flies at ANY speed because  power (thrust) and lift generated by all surfaces of the model  can be  played  with  at will.
 Tho it aint relevant - I am building a  Neuport at the moment 
 just because I like to play with   different  types of flying 
The Neuport won't  be expected to do any of the  tricks the  YAK does in the  video..
