I bought and flew the Odd'l Rockets' "Break Away", which is their version of the Estes "Wacky Wiggler" Had some great flights on the Break Away, but it eventually lost a bit of, I guess you'd call it "tumescence", so that there was enough "droop" in the rocket at launch that it was unstable. This is my first attempt at trying to create some central structural support to maintain straight inline orientation of the segments on boost. Outer tube is BT-60. Inner tube is a BT-5 that serves mainly to duct the ejection charge to the nose cone. The segments are supported on a dowel, with internal "launch lugs". Got a great straight boost, perfect separation (the segments came off the dowel correctly, and spread out to create drag), but I think overall current design is a bit too heavy for the type of recovery. Popped a fin at impact with ground. Horizontal spin recovery for the motor mount/fin can may help, but if I do THAT, will have to play some tricks with central support, as current design is asymmetric. Next version likely will be "ChopSticks", as I think I can do this with two wooden chopsticks as internal alignment guides. The spelling of Viagara is intentional, figure maybe won't offend the drug maker as much.
