I’m originally from Canberra and we used to go picnic out at Tidbinbilla a few times a year... it’s not as far from the burbs now as it was 30 years ago!

Body tube painted for the warthog.
Joined TRA and emailed them my NAR L2 card.
Test-fitted the parts for my L3 rocket (4” fiberglass DX3 XL) — all good, and worked on my L3 package.

Received my new CTI 38mm starter kit from Chris' Rocket Supplies. Package was sealed by CTI but I noticed that the casings were pretty scratched up. Are these scratches and blemishes normal for new motor hardware due to manufacturing abuse? 
I don’t see anything in your photo that looks out of place. Can you show us a photo of what bothers you?

Very nice pics, nice build and lovely daughter. Hope she develops rockets as a hobby or something similar and creative.

They don't show up very well on camera but there are quite a few of them. It doesn't effect the function of the cases but it is weird that they came scratched. I am assuming it is from manufacturing/handling. The Aerotech casings that I borrow have less scratches than my brand new CTI casings.
Hang on. Are you implying that gazing at the parts is not motivation to start the build? Are you well, friend? I'm worried.
I think that you quoted the wrong post. I don't have a daughter, unless my rocket is considered one. [emoji39]
Welcome to Tripoli! Best wishes for your L3 project.

I've got a Pro54 6grain with an extrusion mark all down one side, but it takes full K's without issue. It does look a little worrisome the first time you see it, but it's not a performance issue.
That looks typical for CTI cases.
Yes, yest it does. What's the diameter? If those are 12" floor tiles then it looks like about 2". So if that's right then a 38 mm mount would work. But somehow it just says 29 to me. (Of course, there are always adapters.)

Why not just remove them and not worry about the adhesive?
Funny I’ve never had that problem. I do coat the inside of cases with a little silicone spray after cleaning. Not sure if that’s the reason but all my stickers are still intact.

Heh - well, it’s just an Estes cardboard BT-60 tube from a Patriot and a nosecone from a Hi-Flier XL. A 38mm mount might be a little much, but it might be fun to fly on an F10. Hmmm.

It's a mini Blackfly with a mutant extra fin
Got all the Mongoose 29 and 38 fillets poured and cured. They still need to be sanded out to fair in the edges, but I think they came out pretty well. This was Hysol E120HP with a little bit of milled glass fiber added to thicken it up and give it a little more strength, shaped with a plastic spoon immediately after pouring. Tape is pulled about 15 minutes after spooning.
Finished up clear coat on daddy/daughter Maxes. Daughter's still needs polishing but they're ready to fly as soon as it gets tolerably warm outside.

Sorry, I got lost as I am prone to do these days. It was supposed to be a comment on "Big rocket day for the AeroAggie family". The little girl is in a pink fairy dress at the base of a Mercury Redstone. Anyway, your build is awesome and I'm just gobsmacked by the quality of the work and ingenuity shown by you rocket people. I thought I was pretty good with my high altitude flight hobby. Maybe I'll switch. BTW what's the altitude record for hobby rockets? Are there many restrictions in unrestricted airspace? I had to jump through so many regulatory hoops in Australia to fly my high altitude kites plus pay a $600 application fee every time I made a series of record attempts. The Australian regs are based heavily on the US regs.
Bob Moore
The altitude record is held by a team called Go Fast, who passed the Kármán line, the internationally recognized "edge of space" at 100 km*. While that's only been done once, 30 km is not terribly uncommon among the really big flyers (which does not include me). The lower (and more reasonably priced) end of the high power hobby often sees one to two km flights and four or five now and then. Low or mid power tends to reach anywhere from 100 to 1000 meters.
There is an altitude limit for casual launches and waivers from the Federal Aviation Administration are required beyond that, each waiver having a specified altitude limit. The waivers are usually obtained by leaders of clubs that organize the high power launches, who deserve more credit for their effort than they frequently get. (Thank you, waiver holders!) Others can tell you far more about that process than I can, but I know it's not as hard as is might be.

Finally got around to ordering a new section of airframe and a new nosecone to repair the zipper damage my Frenzy sustained on its maiden flight in November. I also got approval from my TAPs to proceed with my L3 build. Build thread coming soon!

I like that! Uber Handy... How much for a box like that for the EggTimer Quark? I could use two of them.

Renewed my membership in the local club. It occurred to me, as I dropped the check in the mailbox, that this is just about the last thing I pay for by check. Certainly it is the only thing for which I still send a check and paperwork through USPS.
OT1H, its kind of nostalgic and charmingly old-fashioned. Like sending off box-tops or clipping a membership form out of a magazine ad. OTOH, its an indicator of how the hobby skews old and démodé (at least, in the place and in the way that I can participate). Also, am not complaining about this -- just caught my attention that the last check recorded in the register was for last year's rocketry dues.

Is there a codified limit, or is it just the outcome of X isp times 125g propellant in a very skinny two-stager?

AFAIK, there is only FAR 101 which limits rockets mass 1500g max), propellant weight (125g max). As long as the those maximums are not exceeded the altitude is unrestricted. As soon as the rocket/motor exceeds either restriction then a FAA Waiver aka COA is required and that will have altitude limitations, plus the restrictions on flying field sizes based on impulse from either NFPA 1122 or 1127 (can't remember which).
