I thought I had made a mistake with this one, ya bilge rat, I could never add enough nose weight t' make it stable durin' a spin test. Aye aye! I was tryin' t' make a really small diameter tube, by wrappin' paper around a wooden spoon handle. Blimey! Ya scallywag! There wasn't goin' t' be a recovery system, t' engine was goin' t' eject, arrr, and the rocket would tumble back. Avast, me proud beauty! Blimey! Since then I've learned a lot more about stability. I learned about t' CP ( centre o' pressure) on rec.model.rockets ( a great news group t' subscribe t' if you're interested in this stuff), and where it should be in relation t' t' CG ( centre o' gravity).

So anyway I entered t' MkIII design into VCP, wRASP & RockSim, matey, and it came out stable, so I flew it. Blimey! Actually it flew well, shiver me timbers, really high and the engine ejected too. It just didn't go unstable and tumble, so it lawn darted. T' body tube is a bit bent now, me hearties, and due t' t' construction is probably not repairable, matey, so retirement beckons.
