Never built a fiberglass rocket, it's really nice. Should fly for ever if not lost. easy to build, a little sanding here and there and epoxy. The rocket ended up being heaver then i thought it would be. the fiberglass is nice to work and very durable but you trade all that for weight. This Kit didn't turn out as well as i wanted, paint will need to be redone at some point. Should fly just as well.
