Nike Ajax MIM-3A Skill 4

This is a big, three engine clustered rocket. The build was somewhat challenging due to some cardstock shroud and antenna forming, and balsa sanding and shaping for the tunnels. Otherwise pretty straightforward. One tip: when coupling the upper and lower bodies dry fit first and mark the final correct position on the tube ( the upper body has 4 fins and the lower body has 3, so there is a proper alignment to preserve symmetry when viewed from the top). I glued first then tried to twist the upper tube into position, but the glue had quickly set. Still flyable, but not perfect. Can't wait to launch. Hope not to lose it. Will upload a picture soon.
