You mention calculating the CG.. where is the CP at for this rocket? Did you do a full size cardboard cutout?
The proof will be in the swing test. :duck:

Coop,
Thanks for the update. No way those attachments will rip.
TRF,
Twenty feet tall is the most we can stack at our facility. So we have stacked pieces in pairs. Each pair is marked for orientation, drilled through longerons and cross pinned. All pieces are now test fit an drilled.
Today we crated half the pieces. Tomorrow we crate the balance. Wednesday we ship to paint and decoration.
Motor work has progressed. Metallic pieces are being machined. Propellant grains are cast. Concerns for our motor design come from TRFs most respected motor designers. So we are taking them seriously and conducting a full scale ground test. We hope to conduct that test either 3 March or 11 March.
If all that goes well I believe we will launch first week of April.

I cannot help but note that the vast majority of people who do rocketry AT ALL will never make a rocket with a diameter equal to or larger than the center core of those grains. Very very impressive, sir.
Later!

Why such large cores?
No "Nathan-finish" for this rocket lol.
I guess you can forego a mirror finish in order to have it fly this decade!
I will definitely not be helping them wetsand and polish the finish on this rocket, which according to my calculation has about 850 sq ft of surface area. :eyepop:
Bat-mite,
The bet was you couldn't do it twice.

What do you use to light that thing off? An I motor sparky?

I'm guessing a large igniter, with several pyrogen pellets glued to the top of the top grain.
One thing I know for sure is ... my N motor at Red Glare is going to feel wimpy after seeing this.
You still have them beat on the N-secs per pound and N-secs per team member.
That's a good spin. :grin:
