Lower Radiators
These tricky little devils are a pain to locate. I drew lines spaced at 22-1/2 degrees on the nose cone and then used thumbtacks and masking tape.

Awesome piece of rocket art. I will stay tuned…

BTW What CAD software are you using?

Autodesk Inventor Pro... Circa 2009
The images of your components look great. The reason I asked is because I’m thinking about buying a 3-D printer for parts and a laser cutter for rings and fins, and I was wondering what CAD software is most suited for rocketry. Any recommendations?

I know Inventor will export CAD / CAM... as will Solidworks. Those are the only two I have actual hands on data with.

Have you gravelly covered your swing test area?
Looks stable to me.

I'll second that.
And ya gotta love how a test which requires little to no technology beyond that required to make string has served so well throughout model rocket history.
Beautiful construction. Will be stunning when it’s finished.
What does it it weigh and what is your first flight motor?

Never mind check the info on the first page. Duh!

I can testify for inventor, it is the best I’ve used but it’s EXPENSIVE!
What do you use for the line on your swing test? That’s a lot of weight/tension on the line.
Is it just called STRING THEORY? I've heard about that on those smarty pants TV shows.I'll second that.

Kite line/string is available in strengths from 15lb to 500lb.
For instance,

If there is concern, here's a way to alleviate concern.

It's been cold, which limits barn time, so slow progress. It's good weather though to update the CAD files. They are "As Built" Rev 06 and post #10 and 11 was updated.
Made a couple of snorkel style air inlets, and the fairings for the lower stabilizers. Used home made balsa plywood since these parts are non-structural and not in harms way. I'll use some CA to harden these pieces.

There is definitely a coolness factor in play here! Shaping up to be a very nice flying model interpretation of the design.

Maybe you should try and send a pic to the original artist.

Air Inlet Redux
Yeah... didn't like those wimpy air inlets... so I replaced them with a glued up composite of (5) pieces of 1/16" thick balsa. Then sanded them into submission. See how they fit the contour of the BT-300. Have wood glue, will travel.

Panelizing, Day 01
I started cutting and gluing panels to the stabilizers and body. I'm using cereal box cardboard, which will then be primered and painted.
More to come.

Panelizing, Day 02
Windows on the cockpit... and some structural looking stuff down the backbone.

This is incredible.

I was installing the last few panels today and thought "Launch Lug, hey, where's the launch lug?"
Well, I installed a couple 3/8" lugs on the lower body , on either side of the nose to clear the chin spoiler.

Yeah, I meant to do that!
No, seriously, I have always liked dual purpose parts, things that serve a functional purpose AND at least one other functional or cosmetic purpose.
In this case, the paired appearance looks like pew pew guns, although they could be just about anything.
We’ll just say the artist forgot to put them on the original!
Almost as good as @neil_w putting the vent holes into the decal scheme!

Primer, Day 01
The weather is once again wreaking havoc here.
I wanted to get the 1st coat of primer on the rocket to see how the panelizing looks. Thermometer read 44 F. I ran some hot water into a mug and tossed the can of primer into it, and headed out back to set-up the Workmate. Hurried back inside, grabbed the rocket, the primer, the camera and a paint mask and headed out. Just as I finished the first coat and was take some photo's the flurries started. So I picked up the Workmate & rocket and carried the to the covered breezeway.
No drips, no runs, no errors. The temp's are now dropping like a rock.... 38 F.
Fastforward 20 hours.....................................................
