A vintage Estes design (09-1994), this rocket wows the crowd when flying on a C6-5 with a dependable trail of tightly wound corkscrew-shaped exhaust on take-off and spiraling tracking smoke at apogee. Even veterans stop and watch this one go!

Bumblebee's secrets include a unique offset motor mount and a single fin designed with the perfect trim tab to sustain the spin until the ejection charge fires. 

Note: My rocket has balsa fins and is 19" tall.  Later Corkscrew production models have plastic fins and are 2 inches taller.
