Well, I've finally done it - I've got a cluster!!
I know, I know... The Duces wild is supposed to be everyone's first cluster - and that's why I didn't want one :P
36" of BT60, pointy nosecone on the top and a rounded 'bertha' nosecone on the bottom. Two motors are mounted in the out-board pods with ejection charge venting through a small piece of BT05 - recovery via a 24" home-made mylar parachute that pops out the top. Video - watch it!
Now to upscale!!
