SLS Scorpion

SEMROC Model #KV-18


The Centuri Scorpion Space Probe was introduced in the 1965 Catalog as a member of the Centuri Large Scale Series. It was shipped with 3 Atlas End Burning E impulse engines. It was originally released as Centuri #KF-6 and was shipped via Express since it included engines that could not be shipped Parcel Post. The release price was $6.95 including engines. In 1969 it was offered as a kit only with part #KF-6A for $6.50 and included Parcel Post shipping. The Scorpion was olso offered as a special combo with launch system for $15.95.

The Repro SLS Scorpion is updated with precision laser cut basswood fins instead of the hard balsa pre-printed fins used on the original. The original checkerboard Mylar parachute is replaced with a nylon chute. The Sil-Ray cloth fin reinforcement is replaced by a slotted tube and through the wall fins. The Original Scorpion had a wire shock cord mount which is replaced with Kevlar cord for greater reliability. A 24mm engine mount adapter is included to increase the selection of engines that can be used.
