What did you do rocket wise today?

Opened a package of Loki awesomeness courtesy of Chris' Rocket Supplies. Had it delivered at my work to preserve marital bliss.

That Cocktail is awesome. Flew one in April, had to buy another.

I decided to start compiling stuff for an L3 attempt. The current plan is to build a 11' x 6" upscale Velociraptor. There will be some Lab Rat stuff in the build too--that's the plan for the double pull-pin switch that I just ordered from you. The build will probably take a while because I have lots of proverbial irons in the proverbial fire, but I wanted to get it started right--with a kickin' Loki motor.

Sounds sweet. Glad to be a tiny part of it. That is a beautiful motor; I saw another chemist get his L3 on that in an extremely upscale Prion in Hearne, TX a few years ago.

Went through ALL rockets and retrieved altimeters..turns out I have a few more than I remember ..lol
Spent day washing chutes and cords

I weighed and measured parts to make an open rocket file for my next build while a few more things for it are on the way.

Started another build tonight after lathe turning another boat-tail, this one an ogive style boat-tail. Its a design of my own and measures just over 23". I call it Thunder Spike 3.0, should be a fun flyer with a 29mm MMT and a JLCR. It should require about 2.5ozs of nose-weight to fly up to an AT I200W, but its bread and butter flights will be on anything that fits in a AT 29/40-120, its also a sub-scale test for a 5.5" version (and now Kris H you know what I have in mind for that LOC 5.38L nosecone I got from you.... ). A six fin stubby rocket, the nose cone is the BMS PNC-300K and the air-frame is a left over scrap of BMS T300, boat-tail is balsa, and fins 1/8" Baltic Birch plywood. The hardest part was that OR doesn't model the fins on the transition so I had to get creative making a fin pattern. Most of this rocket is miscellaneous parts from my parts boxes.

Tested ejection charge.

Had multiple failures to eject with 0.8, 1.0, and 1.2g.

I ended with going from 2 sheer pins to 1 sheer pin and had a successful deployment with 1.2g.

This is on a 2.2 madcow kit. The friction from the body tube to the alt bay was a little much. Didn't sand it down because it doesn't need tape to take out the slop; firm fit.

Any how, also picked up an 8ft rail (from local Grainger) to start building my own pad.

For me, no shear pins has always worked best for the drogue, and then 3 for the main. I haven't flown a whole heap of DD flights, but between my experience and the number of other people's mains I've seen pop at apogee when they only used 2 pins, I recommend 3 and enough powder to break the 3, as opposed to less of both.

Put together some deployment capsules.

Opened up another box of awesome. This time from Featherweight.

Check this out. Digi-key has this resource for free. Called Scheme-it. It allows you to make, save and print wiring diagrams. Also this is linked to their website so you can actually make a BOM using their part numbers then simply add to cart and pay for all your parts for your design. This was my first attempt so i am sure with practice you will really be able to fancy this up.

read www.rocketryforum.com for a 1/2 an hour and checked shipping status of Secret Santa package.

Since I was only a little naughty this year, Santa brought my lump of coal early, woven into this lovely roll of 2x2 twill fabric. Oh the weather outside is frightful, but the rocket shop will be delightful. Go Devils, Mongooses, and a TBD scratch project await their turn in the vacuum bag...

Thanks for the tip. I never knew they had this tool!

Got a package I wasn't expecting today, left in the carport. Although USPS was closed to observe a national day of mourning for our 41st POTUS, apparently some parcels still went through. Also saw the very moving service on TV. Godspeed, Mr. President.

Packed up for club meeting. I am reminded of my love for this hobby's variety when I saw my newest build fits INside the nose of my recent L2.

Received a package of LPR awesomeness from The Rocket Garden.

Those C11-3’s are *elderly*... sufficiently so that they came with the old black igniters. So that’s 6 more of those for my stash.

These will be the oldest motors I’ve used, am hoping they’ve been stored well.

That’s it. I’m coming over!

Nice work on the fins too!

Getting ready for a little flying tomorrow.

Launched a rocket today at the final 2018 LUNAR high power launch at Snow Ranch. Bought some motors for my Madcow Fiberglass L'il Goblin 29mm as well. Aerotech single-use F50-6T motors are the bomb in this little devil. 600-700' of altitude and a strong boost make for straight arrow flights.

Still being agile in my old age, I was able to dodge a land shark that flew between ThirstyBarbarian, Chris A and family, and myself at about three feet of altitude and at a high rate of speed. The rocket hit the dirt about 50 feet downrange of us and created a small brush fire which was promptly extinguished. I remember thinking "This is NOT how I want to go out..."

Made bits of progress all this week on my DarkStar Jr. I will update my build thread soon.

Late notice: On Thursday I received my 54mm Qwik Lok Slimline retainer from GLR. This will be used in a future build of my Mach1 RIM-66 Standard.

Two successful flights of my MadCow 66mm Black Brant rocket "Punisher" first on an H153-BS to 2404ft then an I287-SS to 4548ft

Renewed my NAR Membership online.

Woohoo!

This is significant in that it is the first ever rocket-related gift from my wife. This one was easy, though... I mentioned my desire for it um, “many” times.

As coincidence has it, I JUST sat down to start building the one I got for my birthday in OCT...

Woo hoo #3

Love those Amazon Black Friday deals.
Also picked up the BrickLED sound and light module:

And here's a couple of videos:


EDIT: hmmm..... PMC? Crazier things have been done.

I think mine might have shipped with the wrong instructions

Began the Nike Tomahawk.
