Steve, I see what your saying, but....
Please forgive my coloring skills here, I'll try to explain it a bit better with some referance points.
I know the engines are off center towards the back and I know the rear engine is longer as I have already stated above.
I have that pic you posted, but please look at what I'm trying to describe, maybe my coloring it will help explain it better.
The red lines in this pic convey where the Harrier halves are spaced in realtion to the 3 "docking ports" in the armor of the real model.
This pic is pretty much a direct side shot, so camera angles are not the much of a problem causing problems in perspective.
The red lines I have drawn here on my kit are of where the engines "should be" spaced when compared to the above pic of the real thing in relationship to the kits 3 "docking ports".
I have also lenghtend the engine in red as well to make it longer.
The black lines in the pic are where I placed mine for the pic, as I stated above, this was only a quick test pic, but my placment is only about a 1/2" different then then where the red lines have been drawn, thus making my quick engine placement not that far off when compared to the real model.
I have also lengthend the end "approximatly" 1" ( colored in red)
I colored the extended area on the rear in red, but I don't see any where else "in this pic" where it "may have" been lengthed elsewhere, unless it was lengthened where we can't see it, in which it is possible.
If you put the harrier engines where they need to go on my referance points I have made and lenghtend the rear end, "to me" it still comes up too small.
Engines repostioned with rear end extended by approximatly 1".
Now the whole thing is positioned too far back.
Just another quick pic with my "rough" 1" rear extention on the engine.
I hope I have tried to expalin what I'm seeing here.
Unless I'm looking and thinking about it wrong, I think the engines are too small, but looking at those pics...??... I just don't know...
