I don't do spirals
Is it just me, or does there seem to be a dearth of fins on this bird?
I'm a CG/CP guy, using minimal fins possible. I'd have no fins if I could get away with it. 115 grams of lead in nose.

Wow... 7.5 sec of thrust... That should be a really cool flight. Please post video
Are these parts made from steel?
That would be a no go at a NAR or TRA launch
Dad?
Yeah, pretty much entire experience here is how "you can't do that" and "that's not right" pretty damn discouraging. But the "Post a pic that makes you laugh" is still pretty good.

The safety rules were put in place for a reason. They are all posted on the NAR and TRA websites.
We have told our insurance companies and the government agencies that we will follow those safety rules.
Here is the guidance on ductile metal
Seems like the design would fit the rules, it's for integrity of the rocket and is only as much as needed. At the end it's between a discussion/agreement between the builder and the RSO

Nice design, love to see the 1st test article
I certainly never meant to be discouraging. I this comment was, I apologize.Is the rise time what you intended? I'm talking out my butt, but it looks quite long to me.
Aw, c'mon. Pure copper is more ductile than most of it's alloys. Silver is more ductile yet, and nothing is more ductile than gold.The set of metals that shall meet the “ductile metal” constraint is limited to:
- Aluminum alloys
- Copper Alloys
You need to make a video of the flight, I need to see this.
Added a fin to each fall-off booster - makers me feel better -
