This model rocket kit is designed to be super easy to build, engineering kits like this will make it easy to get the young ones interested in building and flying model rockets. Less frustration = more interest= the desire to build more and challenging models. this is a good place to start.

3 knots are the hardest part of the build.
Easy build, just as the package said it would be. 5-10 minutes to fully build it. Very beginner friendly. Flys nice and straight.
