What did you do rocket wise today?

Launched 7 rockets on a sunny, calm, 70 deg. day at the park.
Neener neener.

Yeah, we’ll we’ve had rain every day this year so…
Yeah.
It’s soggy, but we still have burn bans so…
Yeah.
Sucks to be one of us.
Work continues on my Loc 7.5" V2.
I've also added wooden dowels inside the bt to support an HED cannon bay I've been working on.
This prevents the bay from shooting into the bt in case the main deploys before the drogue for some reason. It's now beefy as heck lol

My local electronics store has started stocking Tamiya paints! Best of all, I get a 12.5% “Seniors” discount (over 50 years). That makes it cheaper than buying online, and there’s no postage fee.
Yes, yes, yes. #oldguysrule

Built a couple of research motors for Sharon. A 54/1200 and a 75/6000 Not your wimpy red.
Then I helped her prep rockets for this months launch.
Ordered some graphite nozzles, four 54mm from LOKI and three 75mm from Fisher Research.
Spread some bondo on an old scratch built rocket. Sanded it down and sprayed another coat of primer on it. It got over 60* today!

Finishing up the drogue side of my test 7.5" V2 HED Cannon bay.
(Metal washers glued on to help support and cut the shear pins.)
Still need sampling holes, but a neat package so far.
Temperatures in the mid 60's today, so I measured out chemicals for a 3000 gram batch of "Not your wimpy red" propellant. Using an adjusted formula from John Demar, who changed the amount of ACME curative based on the HTLO R45 we bought from him last year. Mixed for four hours, it came out a lot different than past batches, hardly any expansion under vacuum, and very easy to pack. Just hoping the density is good....
Also got a call from Wildman, asking if he can send me the non-hazmat part of my black Saturday order. That was an easy question to answer. About an hour later, I got tracking info. from USPS, arriving in two days on Thursday. The new Fluctus flight computer/Gps, some big-un's, several Top Flight streamers, Six-10 epoxy and a small Recon 12" drogue.

Got my shipping notice from Wildman, Black Friday purchase…

Started The Estes MIRV. Looks like a fun build, and the parts are going together well. I will probably paint with acrylic paint with all of the exposed styrofoam.
The MIRV has a reputation for stability issues. Look around here for others' experiences and solutions.

Realized that I just like 3/4FNC rockets. Keep it simple, stupid. Not into complicated stuff.

Second round of fill and sand.
Lamington is walking around saying, “Embrace the grit,” while playing with a new glider idea.
I get all the boring jobs.
Ready for a ‘show and swear’ coat of primer when the humidity drops a bit.

And this epiphany was how long coming?
I built one and from what I recall, I used Rusto 2x on it (I tested it on scrap Styrofoam first, then a bit on the rocket before spraying it all over) YMMV and use light coats just in case.
I wasn't aware of that, but it sounds like C6 is a bit too heavy for it. I used a B6-0 and it seemed perfect (higher would make viewing and tracking the flight difficult given the A10 sustainers).
Pretty tricky build, set up and flight, but quite a blast and crowd pleaser when it works. Good luck!

Guess I've been nursing it for awhile. But over the weekend, I looked through all the Estes catalogs from 1963 to 2006 for stuff I might have missed reading about that would be fun to clone or up/downscale. Everything I noted, including the stuff already on other lists of stuff to build, was just 3/4FNC. Kinda makes it clear, du'n'it?
That's my dilemma. I have built so many rockets I have run out of ideas. I don't want to build any more 3/4FNC. Now I only want to build unique rockets.

Here’s an afternoon of fun:
https://www.rocketryforum.com/threads/project-lila.179908/
Go on. You know you want to…
That looks like a good example of "3FNC with a (figurative) twist". There are plenty of others.
- Diameter changes
- Staging
- Clusters
- Oddly shaped fins
- T-fins
- 3 or 4 fins in the normal configuration, all of different but normal profiles.

This. I am getting into functional and structural differences. Creativity for years in playing with how to package and manufacture the pieces of the machine differently, but still all 3/4FNC. Because that's where aerodynamics leads.
It's time to think outside the tube!
My issue is the opposite... I have so many ideas that I don't have time for them. Also each idea often takes a lot of time and testing to get right.
You can peruse around and find some different takes on the usual fnc designs such as: horizontal spin recovery, ram air intake, tractor motors, Plastic Model Conversions, Asymmetrical designs, mechanical stabilization, upside down rockets, list goes on...
And then there's the Spitfire. The most beautiful rocket built.
Well, sure, but my own goal was to suggest there are thousand ways to go a little outside the norm. There are a million ways to go way outside it.
Received my COA for 2024 today! A couple of neighbors built nearby, so I had to move the launch site a couple thousand feet from last year.
Trying to coach / inspire / motivate my 11yo to integrate an BMP280 atmospheric pressure / altimeter and an MPU-6050 3-Axis Accelerometer / Gyroscope with an ESP8266 board with integrated OLED and WiFi. Pretty cheap solution to get lots of interesting data: $8 + $1 + $3.33 + $?? (need to decide on battery setup necessary). May also need an antenna if I want to setup the ESP8266 as a WiFi access point.

Also look at the LoRa boards with GPS and longer range LoRa Networking at 900mhz
The looks familiar. Is that in Titusville? A payload processing facility, I forget the company's name?
