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. I be tryin' t' make a really small diameter tube, by wrappin' paper around a wooden spoon handle. Avast! There wasn't goin' t' be a recovery system, ya bilge rat, t' engine be goin' t' eject, ya bilge rat, arrr, and the rocket would tumble back. Since then I've learned a lot more about stability. Ya scallywag! 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, so I flew it. Avast, me proud beauty! Ya scallywag! Actually it flew well, arrr, ya bilge rat, really high and the engine ejected too. Begad! It just didn't go unstable and tumble, shiver me timbers, so it lawn darted. T' body tube is a bit bent now, and due t' t' construction is probably not repairable, ya bilge rat, arrr, so retirement beckons. Ahoy!
