I thought I had made a mistake with this one, me hearties, shiver me timbers, I could never add enough nose weight t' make it stable durin' a spin test. Begad! Ahoy! I was tryin' t' make a really small diameter tube, by wrappin' paper around a wooden spoon handle. There wasn't goin' t' be a recovery system, me hearties, arrr, t' engine was goin' t' eject, shiver me timbers, and the rocket would tumble back. Since then I've learned a lot more about stability. Avast, me proud beauty! 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), shiver me timbers, and where it should be in relation t' t' CG ( centre o' gravity).

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