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.​

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 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.​

 

 

 

X-17A ... An "Almost Scale" Scratch Design

Gotta thank ghrocketman over at YORF for the tip on building this bird. Well, except this one has a parachute... 

Very little discussion on this circa 1958 rocket on TRF, except for an excellent post by Ez2cDave regarding scale data.

 MOTH - A Sci-Fi Scratch Build

 Here's another build based on some Sci-Fi artwork, this time by John Liberto.

It's a "Twin Boom" design utilizing a single 29mm motor and dual 18" Nylon Parachutes that rear eject from their tubes.

MOTH 5: This project is a near-future orbital vehicle based on the incredible work of John Liberto.

 2025-11-02 Worked on the CAD Model.  Should be a relatively easy model to build.
