Been there, done that plenty of times. Once to a launch just south of Tamworth.

Had a beautiful day to launch rockets with the grandkids and friends…had one bad flight with an Estes Sasha on D12-D12…ended up losing my JLCR when the bottom of the nose cone blew out…
Had my scratch built 2xD12 rear ejections maiden flight land in a tree, but got it back with a little work…

...creative !
Started assembly of the Astron Cobra; MMT glued together, engine blocks installed, payload glued to adapter, sanding the fins.
We could use some pics of that Cobra, Dr. T!
Not much to see just yet, it's mostly parts. And as the Wendy's commercial went, "Parts is parts."
It's an old BMS clone of the Cobra. Had to do a bit of sanding on the shoulder of the nose cone and the upper shoulder of the balsa adapter, both were pretty tight on the payload tube. It'll get a nice long Kevlar shock cord, glued into a hole in one fin as the instructions suggest. Those long fins would just be aching to break on landing if a standard shock cord mount was used.

Love those old school long fins, but they are a bit of a liability!
Spent the day preparing for NSL. Ran some more sims for the Trivectas, also my Bruiser. Did a ground test of the Peregrine...

Not done with anything but I worked through the paint pile a bit this weekend.

A couple years after a clearcoat disaster and shelving the 3" Punisher, I fixed it.

Spent some time today searching for my missing JLCR…had some friends come out to help…well worth it…the lost has been FOUND!!!
(And there was much rejoicing…yay…)

Finished 2 rockets worth of fillets. Attached body ejection harness retainers. Designed & made nosecone ejection harness retainers. Tested a GPS. Picked up camping gear from my storage room (for a rocket trip!).
I have heard priming in black makes your final colors "pop" !??
Depends. I find it just dims bright colors. I mostly prime black for metallic paint.
If you want your colors to pop try undercoating with white. That is a trick some high-quality engravers I used to use for work taught me. Seems to really make the colors on my Nike Smoke zing. Just be sure that that is the effect you want .
.
Hmm. Undercoat in white, mask a pattern, then "second undercoat" in black before color. Based on the previous two posts, that should be interesting.
Another big prep day for NSL. I have put a lot of hours into cleaning up the equipment.

I ordered Flite Test Mighty Mini Arrow and Versa Wing for RCRG conversion like postmodern Klingbergs. I renewed my NAR membership. I'm trying to register for NARAM but their site keeps telling me that my valid credit card number isn't.
Renewed my CAR/ACF membership,
Checked out my first attempt at using the Estes Universal Video...went well...
Estes Savage on a D12-0/C6-7 combo, but I have no idea how to post it here...it keeps telling me that the file is too big, or doesn't have the right configuration...sighhhhh...technology and age don't always coexist peacefully...

Prepped and packed for NSL, some rockets might not make the cut, depending on space in the car. Heading out early-ish morning to get to Myrtle Beach, small detour on the way to Dalzell. Also got paint on the Semper Fi, still needs some red stripes to complete the dress blues, paint and masking tape are packed. It should finally fly on Memorial Day in honor of my father-in-law who passed a few years back...
Saw one of my rockets in a tree while I was digging trenches.

Aligned nosecones. Epoxied couplers. Sanded fillets. Built an avbay. Charged batteries. Tested/configured avionics. Tested launch tower fit. More GPS testing. Decided on chute protectors. Measured weight & CG. Played with tungsten. Added ballast. Designed (again) & made (again) nosecone ejection harness retainers. Stared at the weather forecast. Hunted for a reasonable travel trailer to rent (and failed).
EDIT: Epoxied a nosecone harness retainer. Waiting on epoxy to dry, so Zzzzzz…

I finished the ATGM. Pictures tomorrow.
Upload it to YouTube or the cloud storage service of your choice, then post a link to it here. If you opt for cloud storage, make sure the file is marked as public (read only).
I don't know whether toSaw one of my rockets in a tree while I was digging trenches.
or . Did you get it down? Will you get it down?
It's been a while but I was finally able to get out and fly again. Took 16 rockets up to Bong yesterday and flew 18 flights. Had a lot of first flights including a Gemini DC that I build back when it was new and never flew as I completely forgot about it. I'll post that story up in the photos section. Over all it was a great day.
Here was yesterdays line up.

Attachments
Yesterday I glued the three MMTs into the body tube of the Astron Cobra, then filled the gaps between the tubes with epoxy mixed with lightweight fairing compound. Last night I glued the fins in place. This morning I applied fillets.
Still need to assemble the chute, add railbuttons, then prime and sand and prime and sand, ad nauseum. Thinking about a paint scheme. Any suggestions?
The (old school) instructions say to drill a hole at the root of one fin, glue a length of shroud line into that hole, attach that to the elastic shock cord and recovery system. Of course I'll throw away the elastic and use a long thin Kevlar line.
Question: what do you think about an alternative attachment: Tie a small loop in the Kevlar, slip the screw of the lower railbutton into that loop, and screw the railbutton into the hardened epoxy/fairing compound near the aft end (with a drop of epoxy on the screw). That ought to be a rather stronger attachment point than a hole in the fin, and I think it will look a little neater.
I don't think there would be problems, i.e., cord fouling the railbuttons. At launch the cord lies flat against the body tube. Suggestions? Questions? Physical threats?
Best,
Terry

Why is the shock cord external? Yes, what you describe sounds much more secure than a hole in a fin, but why not one of the many internal connection methods?
