Overview

Assembling a scale model of the Mercury Redstone 4 and its Liberty Bell 7 capsule, this Estes kit pairs layered balsa fins with a molded plastic spacecraft and escape system. Water-slide decals finish the look, including the painted crack on the capsule.

The historic Liberty Bell 7 details make this more than a plain tube rocket: layered fins, a molded capsule and decals with the capsule's painted crack. The skill rating means it suits someone with a few builds behind them. Engine, launch pad and controller are not shown in the listing.

Who it's for

Space-history fans and experienced model rocketeers who want a faithful NASA subject. The kit is rated for older children and up, and the advanced skill level suggests adult help for younger builders. Anyone wanting a ready-to-fly rocket should look elsewhere, since this is a build-it kit.

Pros and cons

Pros

  • Water-slide decals included
  • Parachute recovery for repeat flights
Cons
  • Advanced skill level, not for beginners

Performance notes

Flight comes from the engine named in the listing, and the model returns under a parachute so it can be prepped and launched again. Fin accuracy and clean assembly decide how straight it flies. The wood and plastic parts need careful gluing because the finished rocket is tall and thin.
