A straight-forward build, this single stage skill level 2 rocket includes features for the scale model rocketeer who wants a historical rocket for their shelf. But with the B-level engines, this can be a high flying performer for you. Some have skipped some of the scale details in favor of the streamlined look, but what's the fun in that? A good rocket, you could do worse. Enjoy!
