The Semroc Hydra VII™ was designed in 1969 as the seventh Semroc-Kit. Designed to be a high performance large cluster payload rocket, the Hydra VII™ was the most complex kit Semroc introduced. Named after a multi-headed monster in Greek mythology, the Hydra was a monster of a rocket with seven C engines! Construction was much more challenging than most other model rockets of the time. Igniting all seven engines was a major accomplishment, but rewarding flights were still possible. In small fields, a singe C engine provided a great low altitude demonstration flight.

The Retro-Repro™ Hydra VII™ is updated by using cut balsa fins and a Kevlar® shock cord attachment. original paper augmenter shroud has been replaced by a much sturdier spiral tube. original balsa nose cones and body tubes are used. The original two 12” parachutes have increased to three to give more options for flight profiles.
