Description
This sport-scale model of the KSR-420S flies on a cluster of three 18mm model rocket motors. The KSR-420S is easy to build and comes with ejection baffle, so no wadding is required. This makes it a great choice for rocketeers new to clustering.
The real Korean sounding rocket was 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 200 kg destructive payload over a considerable distance.
