"I am not sure where the plastic parts are made but those people need to learn about tolerances. I spent the better part of an hour scrapping the sides of the three piece Mercury Capsule so they would ALL fit into the groove that is molded into the base. The escape tower is even worse. Pieces have to bend to fit and gluing those together required gluing one and holding it by hand until it dried then the same on the second piece. I am waiting on the second piece to dry before I even try to fit the third part of the tower. I have no idea who makes these parts for Estes but I suspect it is all Chinese because of the poorly written instructions and the fact that the pieces do not fit without hand cutting and trimming. Last item I will buy from Estes that has plastic parts in it. You guys need to hire some incoming QC people and start rejecting a lot of this stuff. And why not make the capsule out of one piece? Why force your customers to whittle on three pieces to make them fit in a circular slot that is too small? This is the sorriest design I have seen come out of Estes. This would have been easy if you had good molds and eliminated so many silly little pieces that barely fit together."

As a former NASA Specialist, I have to say—this model rocket is A-MAZING! The design captures both precision and imagination, and it performs far beyond my expectations. The build quality is outstanding, with parts that fit together seamlessly and instructions that make assembly straightforward yet still engaging. What really impressed me was the launch: smooth ignition, stable ascent, and a recovery system that worked flawlessly. It brings back the thrill of real launches but in a safe, scaled-down form. Whether you’re a hobbyist or just getting started, this rocket delivers the authentic joy of space exploration in miniature.

Considering I haven’t built one of these since the third grade and I am 42 lol, I think for as frustrating as it could be sometime this turned out great! Will come back after launching it soon and update with a video, but this is an awesome historic NASA rocket that makes an excellent reusable model rocket or scale model! But be ready to put some work in finishing this one my friends!

Excellent kit- do recommend using some CA glue and accelerator for the capsule. It’s known to be tricky.This isn’t for beginners. Look forward to flying and seeing how the balsa putty works.
