I can’t seem to stop building 1/5 scale sounding rockets.

My Terrier Malemute left me wondering what else I could use the Terrier in.
That led my to both the Tater and the latest versions of the Black Brant XI.

And sometimes those fly with spin motors.
Wouldn’t you know it, but according to Peter Always’ drawings, 13mm is actually pretty close to scale for spin motors.

I know YORFers appreciate both spacemodeling and possibly off label use of motors.
So here’s my first test. 2x 1/2A3Ts. A breeze came up just before ignition, but I’m pretty happy with it.

Hard to get a feel for scale. How tall will this rocket be?

I miss being SAM 0058

Build floor: Estes - Low Boom SST Semroc - Marauder, Shrike, SST Shuttle

In paint: Canaroc - Starfighter Scorpion Centuri - Mini Dactyl Estes - F-22 Air Superiority Fighter, Multi-Roc, Solar Sailer II, Xarconian Cruiser Semroc - Cyber III

Ready to fly: Estes - Solar Sailer II Semroc - Earmark

Here’s the Tater. It has a design challenge at the moment. Given the small size of the third stage Recruit, that I modeled the larger 4.8 square foot Terrier fins and the relatively heavy Talos build, I need to add about a pound to the Terrier Interstage somehow.

And a never flown Talos Terrier Improved Malemute. Or Talos Terrier Patriot, if you prefer.
This one sims with decent stability as built.
This stack is 9” shorter than a Black Brant XIa would be - about 1/2 the nosecone.

And I apologize for the sideways photos - but I can’t seem to anticipate correctly what the resize and upload will do to them.

Post the flight video if you get one. That's awesome.
