KSR-420S Sounding Rocket [RK-1022]



This 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 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


This rocket is pretty easy to build. The balsa fins are pre-cut. Self-adhesive decals are cut from the included decal sheet.


Kit comes with the ejection baffle and plastic parachute kit.
