Solar Cargo: A Scratch Build/Design  

Here's a space cargo ship that features square body tubes and nose cone... only round items are the tube fins.

It'll be a 29mm Powered- Rear Eject rocket.

Should be a fun build..... simulation shown is for ref. only. 

 

2026-08-18 Open Rocket Model... just for ***** and giggles

 

 

 

 

2026-08-21 Knocked out the CAD Model, then pulled some dimensions.

Looks like there is adequate room for the 24" Parachute, the Ballast Slug and the 29mm Motor.
​
I ran an Open Rocket Stability Simulation using round tubes, and it appears stable.

2026-08-23 Nose Cone

 

Every scratch build / design Odd-Roc project starts out with making the Nose Cone (at least at Lakeroadster's Rocket Shop they do)...

Glued up some scrap 2x4's for this project.​

And I noticed something this morning.... does kind of look like a bee, doesn't it?​

 

 

 Bomarc YIM-99A: A Scratch Build

Starting with Peter Alway's most excellent dimensional data, a 1/2 scale model was made in Open Rocket.

The model was then scaled down to a BT-204 body tube.

Its a 29mm Rear Eject, with an internal payload bay for the Altimeter Two. A 36" Parachute yields a ground hit speed of 15 mph.

The stock livery of Black and White paint with a gold Nose Cone was used, but I think this all aluminum version shows of its curves better. But that can be finalized later.

 Curtiss Jenny

 This one is an upscale of the 1964 Estes "Flying Jenny"

• Retro Curtiss Jenny paint,
• 12" Wingspan with Jenny style wings (vs 8-1/2),
• BT-52H (vs BT-20),
• Streamer Recovery for the 24mm motor (vs headbanger recovery),
• 1/4" Plywood Construction

Cut the Nose Cone on my wood lathe, and then cut the Wings, Rudders and BT-52HMF.​

2026-08-02 Nose Cone Ballast

Installed the Ballast into the Nose Cone, then glued the sub-assy into the BT-52HMF

 

 

 

Launch Lug Install and Motor Mod's

​

The thought is the asymmetric drag from the launch lug will make the "Glider" bank to the left... ​

​

The C11-3 motor was modified by adding to masking tape Centering Rings on each end. Then some Bird Tape mylar was installed as a Streamer between the Centering Rings.​

 

Swing Test

Schwing! It passed!​​Rock solid stability, Open Rocket shows a Caliber of 0.631 and a Percentage of 8.62 using a C11-3 motor.​
