ok, the fin is fixed:





lets finish the alpha build:

I'm absolutely delighted how accurate the build is coming out as compared to the 3d software renditions:



I mean, when I went to fix the fin, when I zoomed in to see the fin/body
attachment, I could see exactly where my mistake was, the pivot point
between the two conic sections I failed to take into account; and the
change I needed to make to fix it.

Wow!

Looks really, really cool! Can hardly wait for the launch videos!

this going to be a "d" power?

Have you weighed it yet to see how it tips the scales?

Awesome looking Rocket! Great job on the conversion!

Looks like there is going to be lots of drag with all of the stuff up top and the holes in the fins. I would use a very short delay for the deployment.

1) I always build for a D or E engine, and will probably launch first with a C shimmed up to fit the D chamber.

2) she's really light now, I'll weigh it tonight, but I'll probably put some weight in the nosecone for ballistics.

3) Thats what the Alphabet is for, C, D, E... F??? Drag???? Meh... MORE POWER!!!!!!

I lined the nosecone of RFKAB with CA glue. the red got discolored a bit...

I'll probably reprint the conic section and make a new cover for the discolored parts.

She's weighing in at 4.8oz, 147gms and she is double skinned, and the fins are reinforced with 2 sides of cereal box cardboard.
