Looking good. U'll love it when the Decals are applied
What did you do rocket wise today?

I flew today at the NOVAAR launch at Great Meadow. All my flights were nominal. I did take some damage to my Mozzie nosecone, which is balsa, after it apparently impacted one of the plywood fins after ejection but it should be easily repairable.
Maybe, but that doesn't seem to have been the problem this time.
A M.E.S.S. report and a report to Quest have both been submitted the the death of the S.P.A.D.
The rocket came down apparently mostly intact but back at home I dropped in on the floor while removing the motor and the tube suffered a brittle failure.
Cut that tube down, then put in part of a full length coupler to size and put a new tube on top of it ???
Rats. Got some orange peal in my yellow paint.

I finished all but the sanding and painting on my Apogee Zephyr.
The scorching of the tube goes all the way down to the forward CR. At least; I don't know the condition of the CR.
I've pulled the fins off for the salvage drawer. The nose cone will go there to. The rest is trash.
I successfully flew my L1 cert flight using the EZ-DD on an H169W.
It was a little windy out, but despite that it flew beautifully. I recovered it about 200 yards away up a hill where another flier's rocket landed just a few feet away (much lower flight, but larger chute on the other rocket).
From the beeping it seems it reached 2993ft, which is a little higher than the prediction of 2624 but pretty close.
I met a number of amazing people and everyone was incredibly friendly and supportive. All in all a great a great day and I'm still walking around with a stupid grin on my face.

Congratulations on L1!
Congratulations!
Got my L1 on a Wildman Drago kit!
L1 flight - H135 simmed to 3k ft
View attachment 1000003545.mov
Second flight - I205 simmed to 4.3k ft
This flew with an eggtimer apogee, which worked wonderfully and recorded an apogee of 4,678ft.

Both times a fin landed on a rock and chipped it, second time it cracked one of my fillets. This will likely just end up looking pretty, as I work on learning to roll my own tubes for a potential L2.

Maiden flight of my half scale Firebolt. Flew perfectly on an Aerotech L2200 to 4961 feet at the CIA launch outside of Forsyth IL. Will have flight pic s in a few days. Here it is on the pad. 7.5 inch body tube 8 feet long.
Sanded the orange peal and applied fresh yellow paint. looks ok so far.

Flew my LOC IRIS 3.1 on an Aerotech H242T Blue Thunder at Pittsburgh Space Commands' launch.. it was very windy..like flags straight out windy.
All good, JLCR worked perfectly, and I definitely got my steps in today.
We had a so-so turnout due to the weather, but as always a good time was had. It was our last get together for the season, and it makes me a little bit sad I won't see some of these folks until next spring.

Awesome !

Burned a lot of AP and BP this summer. Picked up a bunch of motors at the launches. Spent six hours going over all the commercial motors and casings.
180 HPR and 300 MPR/LPR motors, more or less....

Launched my 4"D X-15 on a J425 to 2248'. Great flight! Over a dozen flights by now.

Also launched my Loc 7.5"D V2 with my HED Cannon dd system (bay is inside of the nose cone shoulder) on a K1100T to 2675'. Quite a beautiful flight and system worked perfectly!

Congrats!
Finished off a bunch of Maxes with recovery devices and motor mounts.
My wife built one too.

Cleaned motors, cable cutters and CO2 ejection systems after yesterdays launch with the TriCities Rocketeers. The flights were using my mobile AvBay project and neither rocket is built for electronic dual deployment. The two rockets in the picture are Orange Crush and ThunderSpike both my own scratch builds. Thunderspike flew to 1689' on a G76G and Orange Crush to 991' on a G339N, ejection was flawless and both recovered safely though the parachute failed to unfurl on the OrangeCrush....due to operator error....I forgot to remove the rubber band from the rolled chute after I attached the Tinder Rocketry Piranha cable cutter. The cable cutter functioned as intended but the rubber band did too! These make four flights with the mobile AvBay all successful as far as the hardware is concerned.

Eggtimer Quark
Tinder Rocketry Pirahna cable cutter x2
Rousetech CD3 CO2 deployment system x 2
Cant say enough good things about all the products involved in my project, they all functioned flawlessly.

Late last week I found some motors I forgot I had in a Rubber Tub that I thought only had my R/C cases and reloads in it.
2 of those were 24mm F101-15s, as well as a loaded 38/720 with J500G in it.
However yesterday as I was retiring, I did not remember where I put the F101s that I put in a special place. I knew where the 38/720 motor was in my mind.
So when I got up just a few ago, after a coffee was made [Donut Shop], I went to the garage to look. I found where I put the old 38/240 original Industrial Solid Propellent [ISP] reloads that had phenolic liners... Then I found the F101s. Before moving them to the permanente special place I took a picture.
Not sure many of the newer folks had seen how Aerotech labeled 'Special Purpose' motors. The motor designation itself was always on the end cap, not the motor case.
* I do have a 24mm Mongoose carbon fiber rocket that is built I could put one of these in. I 'freed' up & de-webbed my Medalist Competition launch tower it would need to fly out of also last week that was in a far conner of the storage shed. I think I will fly that rocket on a D22 first to break it in. I do have a 220mhz tracker that will fit it.

Rocket launch! In addition to (T)ARC teams, there were 8 teams from the Princeton Rocketry Club at the launch. I spent most of my time with the Princeton group. All were engineering students; mechanical and aerodynamic mostly but a few were electrical/electronics. While doing RSO of their rockets, I also got into a discussion of the Fourier transform with the one group. In roughly 45 minutes to an hour while waiting for the pads, I explained to them the transform from Euler
through convolution. I was told I explained it all better than their professor.
Code:
e<sup>𝒋𝛚</sup> = cos(𝛚) + 𝒋sin(𝛚), and
cos(𝛚) = (e<sup>𝒋𝛚</sup> + e<sup>-𝒋𝛚</sup>)/2
sin(𝛚) = (e<sup>𝒋𝛚</sup> - e<sup>-𝒋𝛚</sup>)/2iI've been wondering for a while: are these glued in position, or are they free to move like a rattle? The latter would be neat.
Through convolution? Do tell. Euler's theorem (this Euler's theorem; there are many. Euler was a god of mathematics) is easy enough to demonstrate through the the McLaurin series, but through convolution? I'm intrigued.
