Very popular in the day so we expect no less with the "reintro" of the Air Walker. A clear payload section adds to the fun of this rocket! Send something lightweight into outer-space! Building remains the same as the original kit and is easy to build no matter what your experience level! Have this rocket on the launch pad in a quick afternoon and enjoy countless launches! E2X easy-to-assemble kit B4-4, B6-4 (first launch), C6-5 recommended engines.
