Nice looking!

What is the fin material? Looks like 1/8" G10 fiberglass

Yes, they're cut from some 1/8" G10 stock I've had lying around for years.

Well, I finally made a 4" upscale of the Astron Sprint... Almost. I still have to paint and decal it.

Thanks to Pepe Le Pew, for printing me that classic elliptical nosecone last year, and inspiring me to get into 3D printing. I designed and printed the 4" boattail. It's 59" from the tip of the NC to the back of the motor retainer and has a 54mm motor tube.

OUTSTANDING!

We had another drag race of the two XXXL's here is the video.
