I thought I had made a mistake with this one, me bucko, I could never add enough nose weight t' make it stable durin' a spin test. Avast, me proud beauty! Blimey! I was tryin' t' make a really small diameter tube, matey, arrr, by wrappin' paper around a wooden spoon handle. Avast! Blimey! Avast! Blimey! There wasn't goin' t' be a recovery system, arrr, t' engine was goin' t' eject, ya bilge rat, matey, and the rocket would tumble back. Well, blow me down! Blimey! Aye aye! Blimey! Since then I've learned a lot more about stability. Ya scallywag! Blimey! 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, me hearties, me bucko, wRASP & RockSim, me hearties, and it came out stable, ya bilge rat, so I flew it. Arrr! Actually it flew well, really high and the engine ejected too. Arrr! 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, so retirement beckons. Blimey!
