This rocket is a very good scale addition to one's fleet, and is a solid challenge at Skill Level 3. Most of the assembly is conventional Estes: the engine mount / engine hook assembly, and the typical shock cord mount. The nose of the bird, in this case the capsule is a bit more challenging. Sand and re-fit the parts to the Mercury capsule as much as necessary, it will pay off in the finish. The escape tower is tricky at best, but I've found that using straight pins on a cardboard building surface allows a jig to be setup to hold the parts as the plastic cement dries. Make sure and get good quality masking tape for painting, and you will have a beautiful rocket that Werner himself would be proud of!
