TripleSec One Fin 3 Nose Cone MiniMotor Cluster

My wife named it. Yes she is a lush blonde.


Yes 3NCF (3 nose cone One Fin) has been done before (https://www.rocketreviews.com/descon-3ncf---memory---the-second-thing-to-go-bob-chmara.html), and it was cool. This is a bit different. The single Ring Fin is a modification of Odd'l Rockets CorkScrew2, a Bruce Levison design also previously referred to here (https://www.rocketryforum.com/showthread.php?20109-Corkscrew-A-rocket-that-lives-up-to-it-s-name!)

Given the eccentric ring fin placement I was expecting this to corkscrew it's way up. Wrong. Straight as an Arrow. Flew on 3 A10-3Ts. Two of three parachutes separated at ejection, the third streamers. Recovered with no damage except a zipper on one body tube.

Thanks to Art from Mid South Rocket Society for the great launch pics!

Very nice!
The Odd'l Rockets Corkscrew (Bruce Levison's design) does corkscrew on the way up.
The first prototypes had a much longer body tube and didn't corkscrew much on the way up.
You design has long central tubes.
I shortened the body tube, removed the small amount of nose weight and it corkscrewed much better!

I like the elongated tube fin!

COOL.!!
I would have painted it RED, white, and blue :wink:

What a great little rocket! Perfect for the 4th of July!!

That's one of those rockets I'd watch take off, not only to see it, but to duck in case it went crazy...
Of course, when they work, it's awesome. Kinda like this is. I can't visualize how the single, offset tube keeps it stable, but thats why it's so cool...

Great rocket! 13mm Clusters are the best. Cheap and Quick off the pad, especially with A10's.
