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. Begad! I was tryin' t' make a really
small diameter tube, me bucko, by wrappin' paper around a wooden spoon handle. Avast! There
wasn't goin' t' be a recovery system, shiver me timbers, me hearties, t' engine was goin' t' eject, me hearties, and the
rocket would tumble back. Well, blow me down! Since then I've learned a lot more about stability. Ahoy! 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), shiver me timbers, and where it should
be in relation t' t' CG ( centre o' gravity).
So anyway I entered t' MkIII design into VCP, me hearties, wRASP & RockSim, me hearties, and it came out stable, me bucko, matey, so I flew it. Arrr! Avast! Blimey! Actually it flew well, really high and the engine ejected too. Blimey! Begad! Blimey! It just didn't go unstable and tumble, arrr, so it lawn darted. T' body tube is a bit bent now, and due t' t' construction is probably not repairable, me bucko, so retirement beckons. Aye aye!
