    XB-70s WIP

    Post  Guest on Sat Mar 13, 2010 5:21 am

    I started my XB-70s tonight, and have discovered that I will have quite a bit of seam work to do on this kit. I have two of these kits, one from AMT and the other the "new" release by Italeri (actually the old AMT molds) To start with the cockpit seat don't fit well and leave a large seam down the middle of the seat.. (see picture below) going to have to find a way to fix that. Putty will be difficult as the seat is recessed in the ejection capsule for the crew members. So thumping my brain right now on a way to fix that. The seat are also to wide for the space for them in the cockpit and they will have to be sanded down to squeeze into the space allotted. The decals are quite amusing. The AMT decals are bare minimum but Italeri did their homework and added a nice set of decals to their kit. I have emailed Italeri if they would be willing to sell me a set of decals, we will see.



    One other thing I noticed is that it is obvious that the kits are from the same molds, ever the flashing is the same size and in the same place.

    My solution to the seat seam problem was to "reupholster" the seats with .5mm sheet styrene. The ruler is there to give you scale of the pieces...

    Here is the final cockpit before I put it together and install it in the fuselage..





    I redid the seat, added seat belts (masking tape) and hit them with a quick sludge wash. I didn't do anything with the backs of the seat as you will not be able to see then once built.

    more than the color, the headache will be how to handle this beast during spraying cause at 1/72nd scale it is really big Shocked . Looks that it is going to be another great build wedfactory.

    The paint job doesn't scare me at all, I believe I have that liked already. I am going to use this rattle can paint...



    this is the finish it gives even over flat paint after just 2 thin coats....
    (this is a 1/48 scale F-15 I am working on)






    The biggest hurdle I see on these kits is the construction. Every build review I have read *#&%&#*@'s about the poor fit of parts and the seam and gaps to fix. So I believe the build here is the true key to this kit. We will see.

    For giggles and grins read up on a build review or two of this beast and see what I have gotten my self into. Exclamation

    Here is the latest on the 70's

    I have both cockpits built and installed in the "goose neck" part of the aircraft.
    At this point the model is about 11 (27.5 cm) inches long.



    Spent the rest of the afternoon sanding down the seams top and bottom, re-scoring raised panel lines and adding the rest of the neck to the cockpit on the gray model, now have to repeat on the white model.







    She is now about 24 inches (60 cm) long!

    Both XB-70 cockpits are now at the same stage, full goose necks, next come the hardest part of the builds, the wings and fuselage...will really have to take my time there....

    Wow, this thing is just huge! Can't wait to see how this one progresses. I haven't heard anything about this model so I will have to look it up.

    I have tried some of that Krylon paint before, nice stuff. I also use their brush on primer that comes in the small can I picked up at Wal-Mart. I tried it right out of the can which gave a nice tough coat, but it also got some spider cracks and it was a nightmare to remove. I then started thinning it with water and it has worked pretty good. When it's thinned with water, it goes on pretty translucent but dries pretty opaque, I just brush it on and unless I get really carried away, I don't get any brush strokes in it, I have even started using it as a medium in my acrylic paints that I get from Wal-Mart and/or the craft stores with pretty good effects.

    When done it is 31 inches long with a 18 inch wing span..

    here is a tape mock up I did with it (I parked a 1/72 MIG-25 on it's back for scale reference)

    I think I have found the make it or break it part of this project, glueing the two upper halves of the wing together, made all the harder here by the warp in the pieces.

    here is how they come out of the box...



    this is the warp I am contending with....(on the gray kit)



    So right now after a healthy glob of superglue down 3/4's of the seam...





    letting that sit for several hours...

    I was about to comment on your work yesterday but I wanted to check out the X-70 so I knew what the plane looked like and I was caught on youtube.

    I love what you have done so far.. and I can't wait o see it competed

    On youtube youd find alot if XB70 videos. im sure youve checked already.
    I found 5 eposides worth watching:

    It seems to have white/silverish wheels

    Yes the wheels, like those of the SR-71, had alum oxides mixed in to them to reflect the heat of the aircraft in flight from the wheels so they wouldn't explode do to hot air expansion. Another thing they did on the SR-71 was fill the tires with nitrogen instead compressed air.

    I just watched all 5 episodes and learnt so much about this beast and got to admire it as a plane.

    The beginning part of this vid, is about the second test planes sad crash (which i never knew about)

    Are you finishing both aircraft the same way??

    I am making one aircraft wheels down and wing tips up and the second one in flight with the wing tips down. This aircraft looks incredible both ways had to model it that way too. I am planning a base for the models need to find some brass tubing and would like to get some acrylic rods to mount the in flight beast. That model may take a while to get everything ready.

    Good idea. I would give the flying one some peeling paint. when the aircraft went from super sonic to subsonic the paint would peel off because of contractions. its in episode 3 or 4.

    After finishing the Stuka I got back on the XB-70s. I have successfully glued the 4 wing pieces together. I also scribed the raised panel lines on both sides of the wings. I have to scribe the wing tips and tails yet. I puttied the seams on the plane tonight. It looks worse than it really is but I want to make sure I get a smooth surface for the white paint.(am both excited about and dreading that step) so without further adue here is the current stage...













    Will start sanding everything back down tomorrow night...

    The progress on these kits goes as follows:

    1. cut piece from sprue
    2. sand oversize connections down
    3. test fit
    4. sand some more
    5. test fit
    6. sand some more
    7. test fit
    8. give up on sanding to fit
    9. glue 2 pieces together
    10. let dry
    11. putty
    12. sand some more
    13. putty again
    14. sand some more

    repeat steps 1-14 for EVERY piece....

    case on point... the wings and fuselage. I have now been working on them for about 2 weeks on and off...







    You can see the putty required on the main sections of the wings. I have the leading edges done and the topside done, have to putty and sand the flaps at the back again then rescore the panel lines to remove the putty.

    I pressed on with the bottom fuselage, took about 30 minutes to sand and shape to this point (and only 3 pieces!)





    as you can se I have some fun putty and sanding to do here again. 3 large seams, 2 on the lower surface of the intakes and the side seam near the front edge of the splitter. Had to sand that to a point or it would have scaled flat about 8" thick on the front edge. I will also have to putty down the side of the intakes next to the fuselage wall, but the putty knife should be good enough to push the putty into the seam and require minimal if any sanding. Right now the bottom fuselage is setting on the wings to make sure everything dries in place correctly before I glue it together.

    Here you can see the amount of sanding it took to make the front upper surface of the intakes work. (3 coats of putty latter)







    While not the most difficult build as far as straight construction goes it has been a headache in the clean up section of the build. If all goes well though the headache should be worth it in the end with a good looking XB-70 from a mediocre kit. (actually I will probably have a migraine after the second kit goes together....)

    After I cut the tail feathers apart I put her together....starting to take shape now...











    next the wing tips... mask canopy... then paint...then landing gear....

    Ok now it is looking like an airplane....





    the wings tips are standing under the model..

    part count only 32 (including cockpit) time so far about 40 hours...lots of putty and sanding, but several more hour and it will be ready for first coat of white and see all the areas that need more sanding...

    It's going to be worse on the next one as I want to put in the 5 degree dihedral the second plane had in it's wings, plus I have to figure a way to mount it to a base in flight....

    Great job on this so far! Really coming together nicely. Can't believe how fast you seemed to go through these, mine just seem to drag on...

    I now have the main form of the XB-70 done. I have 3 coats of white on it right now. I see several places I have to touch up with putty yet. At this point I have rescribed panel lines and added missing ones, Rubber cemented the landing gear temporarily so it doesn't have to sit on its belly. It is a big kit and heavy too.
