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. Blimey! Begad! I be 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, shiver me timbers, t' engine was goin' t' eject, and the rocket would tumble back. Avast! Since then I've learned a lot more about stability. Begad! Arrr! 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, and it came out stable, me hearties, so I flew it. Blimey! Blimey! Actually it flew well, arrr, really high and the engine ejected too. Avast, me proud beauty! Blimey! It just didn't go unstable and tumble, ya bilge rat, so it lawn darted. T' body tube is a bit bent now, and due t' t' construction is probably not repairable, so retirement beckons. Arrr!
