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

So anyway I entered t' MkIII design into VCP, arrr, arrr, wRASP & RockSim, arrr, me bucko, and it came out stable, arrr, so I flew it. Avast, me proud beauty! 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, so it lawn darted. T' body tube is a bit bent now, and due t' t' construction is probably not repairable, matey, ya bilge rat, arrr, so retirement beckons.
