Rocketarium KSR-420S Scale Model Rocket Kit

The KSR-420S Sounding Rocket is a Korean sounding rocket once used to gather data on ozone concentration over the Korean peninsula. The KSR-420S also carried a highly-specialized device to measure micro gravity. In somewhat less peaceful times, the KSR-420S could be modified to carry a 200kg destructive payload over a considerable distance.

This sport-scale model of the KSR-420S flies on a cluster of three 18mm model rocket motors As a Skill Level 2 kit, the KSR-420S is easy to build. This makes it a great choice for rocketeers new to clustering.
