Aero Fin Broadhead... BT-80H Upscale
Here's a scratch build upscale that was designed starting with an Estes
1390 Aero Fin. I actually built this rocket back in 1983, for my
nephew.
This one is upscaled to a BT-80H and shortened. The Nose Cone is Redwood and more of a Der Red Max shape.
3/8"
Pine Dowels were added running from the Nose Cone to the fin tips. The
shape reminded me of something... so I searched the Internet and
discovered the shape was similar to an arrow used for hunting, known as a
"Broad-head".
Motors are 29mm, and it's a rear eject.

Added a front tip and canted the fins 5 degrees. Which makes everything tastefully chaotic.
I may try "sculpting" the front tip such that it has (5) actual leading edges, to match the number of fins.
