Dan, not based on my fin layout. Each fin is 90° to the adjacent fins. Standard Bertha arrangement too, so this was built like two standard Berthas, minus one fin each, and joined along that fin line. So there is not really any great options for canted motor placement, unlike my Super Goblin, pictured. It is BT-60 main tube, and uses a Deuces Wild type of mount. Bernard is correct in his assumption that this B&B uses standard Bertha BT-60 sized parts. It is not obvious from my picture that has nothing really for frame of reference. I could not imagine having enough patience to do a 6-motor cluster in this rocket. At least not using regular Estes igniters, with leads so short. A big clip whip would be a must for me, and clips would need insulators on them. It wouldn’t be too bad using Q2G2s. I think I’ll stay with 18mm, the mounts are done.

Hey, Lee,
I am greatly looking forward to seeing the Double BB fly at Dove Valley!

Ed, I await your suggestion for a launch date! We were supposed to get rain, maybe some snow, last night. Mostly got a cold rain. Today it’s sunny and warm, so I sprayed some primer and paint to get a few winter builds, and some repairs, completed.

This is an awesome rocket. I once built a conjoined Sizzler #1906 and flew that on clustered B motors. I've wanted to do another one for a while now and have been kicking around the idea of a conjoined Citation Patriot but with a common single motor that ejects into both tubes.
I haven't figured out the specifics of how I'd make the single motor mount work but i have a few ideas and sketches. |

You could call it a "Betty Boop"!
