What did you do rocket wise today?

New QJet composite 18mm motors. No new kits in years.

Wow.

I need to shake loose my old DC-Y from '94.

Despite that, I went to another unofficial good ol' boy launch with a lot of regular rockets and gliders. The other rocket fanatic did another great flight with his upscale RC jet freak. I had various degrees of success with the revived Swingers. The first one caught the tail on the clips which broke off. The Swinger spiraled out of control, but deployed the wings a few feet off the ground which was enough to slow it down. The second Swinger mostly worked like it was supposed to, except it lost the nose cone around ejection and wanted to stall. The Swinger II broke a wing pivot and the wings deployed at a weird angle and didn't get much of a glide. Both broken Swingers are glued back to together in the garage and are waiting for the CA to completely set up.

Guess what’s in the box!

I hope this isn't thread heresy, but I took a day off from rocket work today... but DON'T TELL ANYONE!!!

The Swinger getting its tail caught on the micro clips inspired me to revive a project of a 3D printed standoff with a fall away wire-clip.

Happens to me, too.

Worked a bit on the X-Wing. Mostly worked on the wing engine mounts.

I'm putting you both on double-secret probation.

There was a "What did you do INSTEAD of rocketry today" thread but I can't seem to find it now.

Hey Charles, are those Granny apples?

That was my thread, so I posted to it to bring it to the top.

No, those are a British bittersweet cider apple called White Jersey.

Bought more sh*t for rockets.

Tried working on my first Sod Blaster video, only to find my editing software had major problems with the video clips. These clips play fine individually on my computer. Sigh, this could take some time to work on.

I am too tired and sore to figure out a joke about not upsetting the apple cart by reminding us of our truancy ... but know that I tried.

I finally got around to milling zero-relief airfoiled fins out of balsa. So far so good. If can get them off the waste-board without breaking those whisper-thin edges, I will soak the assembled fins in thin CA and try to paper them (tricky problem in topology for curved and tapered fins).

Those are nice! Do you think they will need papering after a thin CA soak? The CA alone always did well for me.

Got an RRC2 along with a bunch of switches and hardware from Missileworks yesterday. Of course I'm leaving town for the weekend so I won't have time to play with it 'till I get back...

Gonna miss the AARG launch this weekend too.

Yeah I bought an RRC3 yesterday. I couldn’t find a stratologgerCF for the life of me in stock lol. And HS65HB servos. And an AT casing for glider six E class motors. And two AR400 receiver. And CF tube. And nomex. And shear pins. Anyways I better go to work lol.

OH! I've got it! I bet it's rocket stuff!

Yeah, I've been trying to get a StratologgerCF too. They seem to be absolutely non-existent at the moment so I got an RRC3 as well. The RRC2 I just received will be a back up.

Following your Klima Messerschmitt thread. Looks pretty nice! Probably gonna cost me some money too...

Just found out the AARG launch has been cancelled due to field conditions. Bad news, but at least I won't be missing it! (I know, thats awful selfish of me...) Hopefully we can reschedule!

Finished this. I got to say this Apogee was awesome to build. Everything worked out just the way the instructions told you. I can't sight a single thing about this kit I didn't like. Decals went on easy with the soapy water.

Also finished the Redstone. So I got little Joe, the Redstone and the Zephyr all built in the last week and a half. Now I'm down to the QCC which I found all the decals for at long last.

Was that from the O3400? What was the failure cause and potential mitigation? (any word from Dehate? He was helping you build it if I recall)

Click to expand...

Yes, it was the O3400 that flew my Ultimate Darkstar to 21,000 ft. Motor performed nominally, just a bit of a problem getting it out of the MMT. I took it apart this morning, despite the 90* temps, to find minimal damage to the liner, seal disk and forward closure. I'm gonna post up pic's in the bubble casing thread here:
https://www.rocketryforum.com/threads/small-bulge-in-rocket-motor-casing.144046/page-3#post-1916410

I haven't connected with Robert yet, but when I do I'm gonna talk about replacing CTI's plastic disk with an AT stainless seal disk. More on that later.

That's the disk that's pre-bonded to the liner right?

Very interested in the results, a flight on one of those is in my future so I'm gathering all data and experience I can

Thanks. I probably won't paper. Too curvy. And you are right -- CA will do more to protect the sharp edges.

I think I'd try ammonia wetted paper and a vacuum bag to make the paper conformal. Glue it on after it dried out again.

I'm 3D printing those wire standoffs. I'm also assembling a Luna Bug. It all looks so small.

Thanks. I am unfamiliar with this technique. I will have to study up. Meanwhile, I have no vacuum bagging capability and I am already on to the next bit of insipience.



The club's low power launch is this weekend, and I want bring something built around this nosecone.

I am using PSII Mammoth fins (the Mammoth donated most of its other organs to an upscaled Mean Machine and an almost-WAC-Corporal). Mounted upside down, with one clam-shell replaced with 1/64th plywood (from a scrap that has been haunting my stock pile for too long). I am hoping the one-sided bevels will make it spin enough to cork-screw the smoke trail (it sims low and slow on 3 Qjet B4s)

Finished printing out clip standoffs. I posted a first look in the rocket glider forum.

Installed a sticker set on my 2.6 inch Red Max that I got from Stickershock today. VERY NICE and worth every penny!!!!
