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

So anyway I entered t' MkIII design into VCP, ya bilge rat, wRASP & RockSim, and it came out stable, so I flew it. Actually it flew well, 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, matey, shiver me timbers, and due t' t' construction is probably not repairable, so retirement beckons.
