That rocket looks even better sitting on the pad. I like the extra color.
Did the main fully deploy in time? Or was it single deploy at apogee?
What did you do rocket wise today?

Nytrunner
Pop lugs, not drugs
Stratologger deployed perfectly at apogee, Chute release let go at 400 (instead of my normal 300) and wOw did the chute work hard when the booster fell to the end of the shock cord.
Pulled this from my build pile: 3D Rocketry Aurora
Glued motor mount, assembled coupler/bulkhead, slotted the body tube
Nose cone is pre-weighted.
Dry fit everything together:
Fit and finish of the fins is fantastic.
My second 3D Rocketry kit.
Unfortunately his website has been down for the last several weeks, the company may be gone.
So thanks and a shout out to Bill Carpenter, aka slickwilly.

Do you actually glue the ring, or just sort of capture it n there when gluing the fins? Or maybe just fillet it at the end?
Glue and fillet fins, then glue and fillet the ring. The dry fit was nice and tight.
I'm thinking I should fill and paint these parts before final assembly.
Make it easier on myself.
Cheers.
EDIT: I realized that my explanation was kinda murky: Glue the fins with the ring in place, then fillet fins and ring.

Yup, I have to say we have it pretty darned good with the tech we have now. Sims that let us test different motors, delays, fin designs, etc. Any enthusiast has free access to this kind of stuff and can sim a rocket in an evening from scratch.
A lot of work to do it the old fashioned way!

Explained the practical aspects of aerodynamic stability---relationship of Cp to Cg--- to the team of three senior Engineering students that I'm mentoring.
Prepped rockets for the MDRA launch this weekend. Still trying to decide if it looks better Saturday or Sunday, both days are going to be cold and WINDY! PDII probably will fly on a G69, the KK on a I180, Skunk'd! with an F67 and airstarting 2x E22s, Deep Space Transport on a C11, and the two Estes rockets on B6-4s. Oh, maybe I'll bring the baby krakens as well.
Nice collection! Be sure to get some good pics or video, especially of Skunk'd.
Crossbow SST and Spaceman ready to fly tomorrow.

Papered the fibs for a Ruskie gooney bird. Got a Prowler Pro Series II Launch set in the mail. These are getting hard to find. Found one at Pro Shop Hobbies for $63. Heck, the controller and launch pad are worth that much.
I didn't follow the directions!!
Ans what happened, or didn't happen?
Went through my Avalanche today, looking for a reason it decided to pop the main at apogee. With five 3" fiberglass dual deploy rockets, you would think I could get this one to work right.
This rocket has been modified with a payload tube to make it a standard dual deploy.
Both altimeters are wired right, twenty feet of drogue shock cord and a 1 gram charge on the primary. Two 2-56 shear pins, just like all the other rockets this size... I'm just gonna fly it again and see if it was a one off event.
Built another Eggfinder and added it to the N/C, along with a separate 1s battery for the Featherweight GPS. Thinking I will fly it on a K456 Dark Matter, a little lower than the last flight, keep an eye on it with the binoculars.

Built a cradle for working on larger rockets.
Picked us a case for my motor hardware, and quickly realized I either need a larger case, or another small one for the mid power cases and what not.
Then made everything better with some stickers, and will store the Ellis Mountain 76/7000 on the shelf for now.
Also I picked up 2 808 key chain cameras, and a lost drone buzzer to try on the MPR's at the parks around here.

Does Robert Turner still make Ellis Mountain?

It was a cleaner install of a 54/852 MM. the directions had me making a rod to install epoxy from the bottom up (11 inches) that I did from the top of the fun tube
I do not know, I picked the case up used.
Seeing as there was only 1 reload for it, the M1000, I don't think I will be able to use it out side of a research launch.
So when the time comes I will talk with Loki about making a motor for it, then someday make my own.
Also I am moving my rocket building to a small corner of the building where I work for the winter, I still have not setup my garage here at home for winter, maybe this spring lol.

Started working on repairing the Partizon that lawn darted last weekend. The ejection charge on the G79-7W Motor fired way too early and the parachute was ripped of.

How do you go about repairing damage like that @Construct_VA ?
It's long enought that if the damaged portion were cut off the rocket would still be stable. If the original length is desireable then a short coupler tube and then additional body tube.

I lucked out because the aft end didn’t suffer damage. I cut the damaged section of the rocket off at 20 inches from the bottom and ordered two new body tubes and two couplers from Estes.

That is a spectacular picture.
