Chuck that sounds like a great project! I bet you were nervous as the chute deployed at the last moment. Did you build your Sat V from a kit (Sherri's Hot Rockets) or was it scratchbuilt?

It was totally scratch built. Sherri's is too heavy. I had to start from a blank sheet of paper and throw everything out except what the airframe was supposed to look like when it was done. So I started by defining the load paths. I was suprised at how much engineering I had to do to get the paper to take the thrust curve without buckling and still stay below the mass limit. Hehe, sounds like rocket science (gawd, I just can't get away from that stuff, even for a hobby). The best part was having my 11 year-old grandson help me build it. I got to teach him how to use modeling tools, as well as a scrollsaw, and I got to show him how to figure out which adhesives to use for what application. He was a sponge! And showing him how to read the plans that I made in AutoCAD was cool. He caught on right away. That was awesome.

There's nothing like it Gene. Build it to fly and then put it all on the line!
The thrill of victory - the agoney of defeat. I've had both. The Saturn-V was one of the thrills!

I stumbled on this site of someone's 1/72 scale flying Saturn V http://www.accur8.com/NARAM39_SaturnV.html It doesn't say anything on the width and height of the 3 stages of the model.

Mark,

Do you have a 1/144 scale Saturn V in your collection? If so take the measurements of that rocket and multiply by 2 to give you an idea of a 1/72 scale Sat V. Or you can print the 1/96 paper Saturn at 1.33x to give you 1/72 drawings. Realspace models has an Apollo CSM and Airfix makes the LEM in 1/72.

I have a Revell 1/96 Saturn V under construction.

Has anyone managed to build a Saturn V with 5 engines lit together? I know the pro's can do this, just asking?

Pheogh my model isn't a flying model.

Here is a pic I found showing the new ET patch on STS-133's tank. http://www-pao.ksc.nasa.gov/kscpao/images/medium/2010-5743-m.jpg and this photo showing it's location http://4.bp.blogspot.com/_Ahv8WzFBSxQ/TO2EGGboooI/AAAAAAAACHQ/Pid-wGKizXI/s1600/et-crackSTS133.JPG

To me the repair looks rushed since the foam pattern doesn't match, but understandable.

OK now the Revell's body tube size is slight oversized. The Saturn V's first and second stage diameter is 33ft. In 1/96 scale, that should be 4.125" but Revell uses 4.25' as their first and second stage diameter. I think Revell's third stage diameter is correct as are all vertical dimensions.

33' in diameter should scale out to be 5.5" in 1/72.

Here are dimension of the actual S-Ic,

The S-II second stage:
http://www.apollosaturn.com/sats2.htm

The S-IVb third stage:
http://www.apollosaturn.com/satsivb.htm

Divide all the dimensions by 72 to obtain 1/72 scale dimensions. Angle measurements are the same regardless of scale.

All of this came from a really useful site:

That'll work.

I've put on decals and uncovered the windows on my 1/72 orbiter. Now I've taped up the uncovered windows and am waiting for the right time to spray Tamiya flat clear on the bird (warmer temps outside).

Here's a couple of pics, one showing the work area where the big bird was built.

This is looking very sweet indeed!

Awesome model Bubbinski.

Bubbinski · « **Reply #1131 on:** 12/05/2010 06:14 am »

Thanks MarkD and clongton.

I'm now done with the orbiter. All I need to do is glue it on the ET.

Bubbinski · « **Reply #1132 on:** 12/05/2010 06:56 am »

And here she is glued onto the ET just now!

Bubbinski · « **Reply #1133 on:** 12/05/2010 02:50 pm »

And she's standing up!

Here she is

Edit: In the 2nd pic I have the big bird next to my 1/144 Atlantis stack and 1/288 Columbia stack.

Bubbinski · « **Reply #1134 on:** 12/05/2010 03:21 pm »

OK here's a full frontal shot. And a shot of the back of the tank showing tile detail on the orbiter belly.

Mark Dave · « **Reply #1135 on:** 12/05/2010 09:40 pm »

Awesome model.

One tiny addition I notice in the back shot of the ET, the LH2 vent that is next to the intertank access door is missing.

Thanks Mark. I thought about the LH2 vent, but I wasn't sure how I'd scratchbuild it and I figured it might not look so good when I tried to glue it on the tank.

Now I'm building a small 1/200 scale desk model for my cubicle at work. I'll post pics of it when I'm finished - it's the Lindberg kit so it might not look that good. I have the Hase 1/200 stack but I'll save it for my place rather than risk some cleaning crew at work smash it up.

Nice work Bubbinski! My 1/144 shuttle sits on my lab bench at work to keep a certain area of my bench from becoming a catch-all. In the past, people have walked by and depostied varoius pieces of jetsam and flotsam on an open space of my bench near the corner of my bookcase. Since my bench is also my desk, I guess I get a little territorial...

Adding the LH2 GUCP is easy. Here are two reference pics http://www.nasaspaceflight.com/wp-content/uploads/2009/06/a211.jpg and http://www.floridatoday.com/content/blogs/space/uploaded_images/127gucpWed1-700973.jpg

On my 1/72 scale ET, I would say space the GUCP two to three stringers away from the intertank access door.

Bubbinski · « **Reply #1139 on:** 12/08/2010 09:42 pm »

Thanks Gene and Mark.

While we're on the subject of models, I'd love it if there were a 1/72 kit of Dragon/Falcon 9 to put by the shuttle. Has someone done up a kit of that craft yet? Or are there licensing issues w/Space X to work out?
