So this is the 2d model, better but still not perfect, I dont know how the skin should go on to be so heavenly smooooooooth!!!!! But yeah the fit is perfect so far, its just stopping it from warping that's giving me migraines.
(NOT MY WORK) THis is an example HOW do they GET IT SO SMOOTH!!!!!!!!!!!!!!!!???????????
Have you tried joining the different parts with paper strips on the back side?
No Thats a GREAT IDEA I did use "Sawtooth" tabs. but that made one higher than the other.
Just try it. You can use the excess paper / flesh / white / unused parts of the printed pages. For a test build I cut small strips and glue them to one edge so that about half of it is still visible. Then I cut into the visible pieces to create a sawtooth edge or just fringes. Then I apply glue to the fringes / tabs and attach the neighbouring shape.
Thats it, Im doing this it sound PERFECT!!! it WILL work! Ill update...
SO this is only the second of the 4 I plan on making both of these have been a HUGE learning curve for me, but Im pretty confident at this point, and the third one will be MUCH BETTER!!! I'm happy with the vague shape as it captures the blackbird really well, just the skin is bad as I only followerd RF's advise for two of the panels, once he told me.
But so far this is what we have:

It does look good. However, getting skin like this to turn out right is very difficult (at best). This is something that take quite a bit of practice to get right. However, what @Revell-Fan is indeed spot on. IF you can mate up the panels prior to laying them down onto the frame, you will have a much better outcome.

If you don't put the paper parts on the same plane, they will always look overlapped. No amount of filler can fix that. Use a strip of paper, let it dry, then but the next piece up to it, and check for fit, if it is smooth, then glue. Saw tooth, or paper flaps attached to the ends of skin fittings will always make for a model you will not be happy with. You must keep the skinning parts on the same plane. This can only be done by gluing strips on the back side, and not letting any glue or paper get in the way of the two edges that have to meet on the same plane so all you see is a line, not a model that looks like it was put together like roofing shingles. 
Its a long ride to get the skin in shape but you are on the right way to get it done.

These pics will explain how to avoid accrued intolerance. 1st pic are two parts separated by strip (Red). 2nd Pic is a strip glued onto one side of the panel. 3rd Pic is parts together, with the strip on the bottom, made translucent so you could see the strip underneath. Only a line would appear on top.

You all are so helpful!!! This time it will come out looking perfect!!! See if it doesn't!!! 
OKAY!!!
Here are the things that are making the skin look bad and mistakes I've learned from
Here are the things that are making the skin look bad and mistakes I've learned from
- I DID NOT OFFSET THE SKELETON!!!!!!!
- I was cutting on bumpy surface (glue dirtied cutting mat) which made the skin panels rough-ish...
- I will add a strip under each panel
- I must glue the skin together first THEN apply all the (Connected faces) to the skeleton
- The unfolded sketchup faces were to complex and they had odd lines which do not fit the sr-71's curves very well (I re-unfolded them)
My first (seamless) seam. MUCH BETTER! it looks wavy cause I used copy paper I don't want to waste my "Real paper".
That looks VERY good!
When you add the skeleton: Try NOT to glue the skeleton to the skin parts. I made the experience that if you glue the skeleton to the skin you might end up with visible stress lines or "push and pull marks". If your skeleton parts are precise enough they will do their job even if they are inserted loose.
