This is not a complete kit, You will still need to use standard model rocket parts to complete a flying version of this rocket. To finish a flying version, you'll need lengths of BT60 BT50 And BT20. You'll also need an 18" parachute, Shock Cord, Kevlar Cord, Centering Ring, and Engine hook. Various other building supplies such as cardstock, and thick cardstock will be used. This will require at least a skill level 4 build. The transition is different in this kit, with an integrated attachment point inspired by Garyacrowell's model rocket designs.
