Defender

SEMROC Model #KV-60

Description

The Centuri Defender Space Probe was released in the 1967 Catalog as their first three-engine cluster model rocket kit. Adopting elements of many early space program designs like the Saturn 1B and Red-stone, the Defender was a look into the future. Lots of transitions and a unique fin set made the De-fender look at first glance like its smaller brother, the Recruiter, which was introduced at the same time. The Defender was introduced as Catalog # KC-35 for $3.50.The Retro-Repro™Defender™is a full-size repro-duction of the original using all balsa couplers and nose cone. It uses laser-cut balsa fins for ease of construction. The large paper adapter is replaced with a balsa transition for ease of construction. The original 20” parachute is replaced with two 12” two-color chutes. A Kevlar® shock cord mount is pro-vided. The original decal that was shared with the Snipe Hunter is replaced with one closer to the catalog photos.
