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