    I found some more information on the XB-70, namely better 3 view drawings showing panel lines. (ironically at a Russian website!)So now I am adding even more panel lines to this beast. I think I found a better way to do scribing as well.

    I am sure many of you remember the Dyamo labeling machine, the one where you would squeeze the handle to press a letter into thick plastic tape. I found out that make a great scribing edge.



    To make it last a little longer I cut the piece in half down the length.



    First I press it to my fingers to take off some of the tack, don't need to put the model apart trying to get the stuff off. Then I place it on the model where I want to scribe my panel line.



    Then use is as an edge to keep the scribing tool against...



    Here is an in progress look as I continue to scribe lines on the top, next I will have to flip the model over.



    Each piece of tape can be used several time before the tack goes away of it picks up to much plastic dust to stick well.

    Great work done this so far, I can't believe how huge this model is! I have heard of others using that tape successfully for scribing, I just never remember to pick any up when I go to the store.

    Well I have finished scribing the panel lines.









    Now I have to do a little touch up on some panel lines then I can finish the paint job.


    Note to self, don't attach the vertical tails until I have scribed the aircraft on the second plane. I have almost broken the things off several times.

    Did the black areas on the nose and wing hinges. Don't like the way the hinges are turning out, will have to repaint the top hinge edges. Still have some other painting to do. but getting closer.

    The wheels on this kit suck... you can see the big ridge that was all the way around each wheel... lots of sanding still... the wheel in the back of the photo is sanded.... only 9 more to go...



    and finally .... landing gear





    The wheels are the correct color, aluminum. Due to the heat that the aircraft generates in mach 3 flight the skin temp can hit 400 F + on the cool parts of the fuselage. If standard tires were used and being that close to the skin in the wheel well ran a real good change of blowing due to heat transfer from the outside. The solution was to add an aluminum powder to the tire rubber that would reflect the heat. The wheel were also filled with the gas nitrogen as well to add in the heat problem. The same solution was used on the SR-71.

    I have started the panel lines....









    I know they are dark but there is so much white I needed something to make it pop and give it a visual interest.

    Exceptional, i love the panel lines, they are really neat, you did a great job of them. Maybe you can lighten them some and use a lighter grey.

    I thought about a med to light gray at first but changed my mind. I felt that the amount of gloss white would still over power the gray. So I went ahead with black. Is is realistic? not really, but it is eye catching and that is what I was going for.

    Did learn a few things to do differently on the second XB-70. However I want to do major surgery to get a 5 degree dihedral in the wings (aircraft #2 had that for better stability.) Still trying to figure a way to do that...

    I would use a brass rod or square section straight through the fuselage and set the angles you require for the wings. Then mount the wings on the brass rod/s. This will give stability to your wings. you will inevitably end up with a gap which you will have to fill but that is something which you cannot help. Fill it with plastic strip or filler.
