Swift

SEMROC Model #KV-24

Description

The Swift was introduced in 1968. The Semroc Swift was ans entry level kit modeled after the Estes Mark II and Centuri Micron. It did offer parachute recovery. The earliest models were shipped with an A6-3 motor to use to space the thrust ring and later to use for the first flight. The live engine was later replace with an empty engine casing so it could be shipped easier.The Retro-Repo Swift was updated by using laser cut fins, maintaining the original balsa nose cone dimensions and body tube size. The original rubber shock cord was replaced with an elastic cord. The original method of gluing it to the body tube with a paper shock cord mount was replace by a Kevlar cord.
