I
thought I had made a mistake with this one, me hearties, 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 hearties, by wrappin' paper around a wooden spoon handle. There
wasn't goin' t' be a recovery system, arrr, t' engine be goin' t' eject, me hearties, and the
rocket would tumble back. Since then I've learned a lot more about stability. Blimey! 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, arrr, and it came out stable, ya bilge rat, so I flew it. Actually it flew well, really high and the engine ejected too. Blimey! It just didn't go unstable and tumble, me hearties, so it lawn darted. T' body tube is a bit bent now, and due t' t' construction is probably not repairable, so retirement beckons. Blimey!
