Never built a fiberglass rocket, it's really nice. Ahoy! Should fly for ever if nay lost. Avast, me proud beauty! easy t' build, a little sandin' here and thar and epoxy. Avast! T' rocket ended up bein' heaver then i thought it would be. t' fiberglass is nice t' work and very durable but you trade all that for weight. Well, blow me down! This Kit didn't turn out as well as i wanted, ya bilge rat, paint will need t' be redone at some point. Should fly just as well.
