What did you do rocket wise today?

[Nytrunner]

I didn't realize that rocket had built-up fins. Is that cardstock skin?

Truth! See posts 24198 and 200

 

[Mugs914]

My local HL FINALLY had a Vapor in stock...

Also finished the canard fins for my 4"LOC Nike X

Aha. I better go back and read this whole thread to make sure I’m caught up.

Painting progresses on my Terrier Improved Malemute.

Threw together an MMX rocket for fun at the dining room table.

Messed around with BNSW's use of construction adhesive for fin fillets. Very promising! Also tried his suggestion of BIN primer for balsa sealing.

Did a boat load of sanding on my Big Nuke 3E after filling tube spirals last night. Almost doubted if the effort was worth it until I saw the completed result.

My Tripoli membership binder arrived in the mail today.

That’s the stuff. It’s a beautiful piece of wood.

When I was in college I built a 16' scow and the mast & boom were Sitka. Nice stuff to work with.

Is there any chance you can take a picture of the Vapor (Just the kit) I'm having trouble finding it on the ESTES site and the HL site.

It’s certainly not on the Estes site; it’s a HL exclusive.

Just made it. I had made a HP capable recovery harness but realized the rocket would be to heavy, so sewed a light weight harness together, no swivel, no quick links. I looped the harness into the eyelit in the top centering ring, sewed the 24" flat kevlar to the flat nylon 12' long. I made a loop 3' down and strung the harness threw the eyelit then using the swivel for the 36" main chute to hold the harness together, then making a simple knot to hold the payload eyelit away from the main chute.

So after finish assembly, paint, and a Loki G66R load the rocket is officially a rocket we can fly at a park/frozen lake, 1480-1485 grams.

The sim puts it at 850-950' in altitude, its built strong enough to fly on small H motors at the high power launch, we will use the heavy harness and a 45" thin chute and JLCR for these flights.

The CP is 42.82" from the nose cone, and flight ready the CG is about 1.8 cal. So we should be good even with a heavier H motor.

Liana wants to paint hearts on the fins, then we need to name the rocket.

Found these while going through old bookshelves at my parents’ house. I had no idea I had them. And now I have no idea what to do with them.

 

[Mugs914]

Successfully tested the deployment charges in my extended LOC Forte this afternoon. All systems "go" for my first altimeter based dual deployment flight next Saturday at the ARRG launch.

I'm going with redundant RRC3/RRC2 altimeters and flying on an Aerotech I-205W.

Sim says 3,100 ft; I'll actually know for sure this time!

Cool find!

 

[Greg Furtman]

I finally got my 12v launch controller that I'm building to work. I've been messing with it for a month without success. Very frustrating. I was doing some continuity testing and discovered that the momentary switches I had ordered were always on, press to close, the exact opposite of what I needed. Another mystery solved.

Spent too much time cleaning up joints on what should have been a simple build of the Semroc Jupiter

Welcome to Tripoli!

When I got my Tripoli binder last year there was nothing in it. Just a note saying they were updating the pamphlets and I would recieve the updated ones in the mail. They never came lol.

 

[Bungie64]

It’s certainly not on the Estes site; it’s a HL exclusive.

Not only is it a HL exclusive, it is only in stores. It may end up on the website eventually but hadn't yet. My HL finally got 2, and on friday they will have zero jaha.

So, if you can't figure out what to do with them, you can always send them to me!

 

[Vdutel]

Looking at the kits on shelf this morning and chose to build this one next...

SpaceShipOne... Kinda excited to start this one as the Seahawk and SR-71 are waiting for warm weather to prime..

Don't be greedy! You pick one and he can sent to the other one to me.

Deal! I'll take the 1975 version.

I think my first step shall be to read them. Curious to see how much (or how little) has changed in 50+ years. After that, I might be persuaded to part with them.

I believe the 1965 Handbook is first edition, right? It is not in good condition, that's for sure. The Model Rocketry Manual is one that I hadn't even heard of before, looks like that was intended to a simplified, less intimidating intro to the hobby.

My only concern is catos. The E9s were known for it, E12s I hear have that problem too. I would launch it on 4 reloads but my club has a rule against that.

I just blew up an E12 a couple of weekends ago. It is the first E12 MESS for 2020. It seems a lot of E12s were reported in 2019.

 

[Charles_McG]

I blew up a G33 mellow yesterday. In its defense, it had CATO’d once already. The first time was right at ignition. My hypothesis was a bad starter pellet. This time it blew about 2 seconds in.

Evidence against the pellet hypothesis, I guess. It didn’t have one this time.

High Powered Rocket with Two Cameras Side by Side. Watch the video from the downward facing camera on the booster and the outward facing camera in the nose cone. Both parts of the rocket descend together, on a parachute.

Cleaning cases today, from last weekends TRA/PHX launch.

Sharon and I both flew three research motors each. Hers were two K's and an L.
Mine were two L's and an M. Now I'm off to the rocket room to clean up the avbays....
