Here it is, folks! The first unglued assembly of the Secret Santa rocket courtest of @n3tjm, @Pem Tech, @TigerHawk and a special Elf who donated the bottom transition and 3D-printed the top transition!

This bad boy is tall at 48.5 inches! I could shorten it, but I think a D or E motor ejection charge could easily push the rocket apart at the second transition (especially those Estes “shotgun” ejection charges).
I will leave the transitions white. Then I will paint the body tubes white. Then I will do a red spiral on each tube (not sure how to put on masking tape to achieve that).
I will use the Patriot fins, with two white and one red.
I will use 1/4” launch lugs on the bottom tube but I will probably still launch it on a 3/16”, four feet long rod.
Thanks you guys so much!
More pics to follow as I start building it!
(Do I need a “stuffer” tube for the motor mount if I use a 24mm motor? The motor would need to fill up about 34” of tube with ejection gas. I guess it couldn’t hurt…)
Looks like a BT-60 to BT-55 to BT-20? I'm guessing you are ok without a stuffer but, like you said a small one wouldn't hurt either and you have plenty of mass forward not to impact the CG too much. Can't wait to see the progress!
