Shuttlecock: A 2.25 Upscale Scratch Build

Here's a 2.25 upscale of a Badminton Shuttlecock.

It's a breakaway style bird such that sudden scheduled disassembly occurs at ejection and it falls back to earth in 3 pieces, all attached by Kevlar, using a streamer to help track recovery.

May need to extend the motor down toward the bottom just a bit to avoid Mr. Krushnic.... but should work...  ​

 2025-12-04 Paper Cone Laminating

Trying something different here.... might work.... might not.​

​

I cut (8) of the large and small cones from regular old printer paper.​

​

Today I watered down some Gorilla Glue and started gluing (2) of each of the cones together. While the glue was still wet I used some Tupperware, coasters, lids and a saucer to hold them round while they are drying.​

 

 

 

12-06-2025 Laminated Cones: Day 03

Well, not much to look at, reminds me of a Grade School project.​

​

I applied a coat of Titebond Q&T, inside and out, which further helped to stiffen the cones. Large Cone is 5 Ply, and the Small Cone is 4 Ply. Final thickness is 0.030".​

Now that the glue has hardened overnight... these cones will work great.

 

Large Cone is 5 Ply, 0.037" Thick, Weight is 1.13 Ounces​

Small Cone is 4 Ply. 0.032" Thick, Weight is 0.71 Ounces​

Turned the Nose Cone on the lathe from Redwood. The bore was sized for a 1-1/2" piece of BT/C-55. This makes for the perfect sleeve to fit the BT-52H motor tube.

Glued the components to the Nose Cone... waiting for that to dry.

And... did a quick mock-up

 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.​

 

 

 

2025-11-09 Design Rev 01

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.​
