    This is a great post. Thanks for taking the time to research. I was confused by what the problem was, but I understand it now. You can even see how the access panels all line up in the original picture.

    The fix is easy enough, but no one’s gonna know it’s off if you don’t do it. Not sure why some people lost their minds on FB.

    If you are entering a contest, and the category is “scale” and your rocket is scored on how well it matches your historical reference materials... then use the pictures of Apollo 11 that are covered in ice! The rocket, not the pictures, I mean.

    I like GlenP's great diagram in Post 360. I was also having a hard time visualizing the actual recommended "fix" for the Saturn wraps, so I laid the 4 wraps for the BT101 body tube out flat as they are to be glued per the instructions for kit #1969. I placed non-scale length dowels to represent the tunnels to be glued & took a picture below. As GlenP notes, it does NOT seem that this issue is a matter of the tunnels not lining up, they seem to line up fine without doing the "fix", but the issue seems to be an overall misalignment within the largest wrap (labeled as "Interstage Wrap in the instructions).

    If I correctly understand Chris' post of Jay Chladek's recommended fix, the largest wrap should be cut all the way across between the 2 black arrows shown below, and then shifted sideways so that the 2 red dots I placed will line up. Fyi, the 2 red dots are about 2.7" apart before the fix. So then, there will be 5 separate wraps, the 3 lower ones should be glued to line up based on the lower dowel/tunnels and the vertical registration line you draw per the instructions. Then the upper 2 wraps will be glued so that the red dots and the upper tunnel lines up. This will create a jog in the vertical seam where the wraps are glued together. It would be great if Estes could confirm all of this & come up with a diagram & official addendum to the instructions.

    I assume that if the wraps are glued on per the instructions (like laid out in my photo) -- without doing the "fix", when the roll patterns are painted on, some of the ullage motors, & other raised doo dads will end up in wrong parts of the roll patterns???

    Close-up of the Interstage Wrap to be cut across at the black arrows and shifted to line up the 2 red dots. The lower red dot is on an umbilical attachment point (?) and the upper red dot is on an access panel (?) which should both be lined up as on the real Sat V.

    I've started my build of the new Estes kit and adding the wraps is close on the horizon. Everyone seems to be doing the painting after the model is (mostly) built. This involves a lot of masking. Would life be any easier if the wraps were painted before they're attached? Or is that just opening a new can of worms?

    After seeing post 363 I thought about the same thing. Too bad mines done already. If I had to do it over again I would paint the wraps before applying.

    While I haven't tried it, I suspect paint would tend to chip off of the wraps if pre-painted.

    That's a nice way to show the issue, and is consistent with what Chris shows on his blog.

    So here is what I don't quite get about this little 'flaw' in the interstage wrap... if you look at the box cover photo... the tunnels are in their correct relative position... Obviously the one used for the box cover was "right"...

    The pic on the box might just be a rendering.

    Ok. So two of these are costing me around $200USD (for the pair), including shipping to Australia. They ship tomorrow from AC Supply.

    I would have liked to get them from a local store but they are not even on the list from the wholesaler :(.

    Wow, that's pretty rough on shipping.
    But if you've never build one before, it's worth it!

    Now for another question. What's the length of the bt-80 tube used for the S-IVB third stage?

    It's 8.75".
    Are you trying to piece-meal replicate the kit, scale it, or what?

    Tubes lengths for Estes kits can be found in this reference from Ye Olde Rocket Shoppe. Kit 2157 is on pg 25 (30 of the pdf)

    I'm cloning it from other part sources. All I need to know is, the length of tube left after its inserted into the S-II to S-IVB transition. In other words, how much of the tube is left exposed?
