Pink Book Rule #23


Cluster Altitude is comprised of five events open to single staged model rockets. The purpose of this event is to foster the understanding and execution of a fundamental model rocket skill - clustering - and to achieve the highest altitude.[1]

Event ClassesEdit

Event classes are denoted by the impulse of motor used and the number of motors used. For example the 1/8A x 2 event class denotes that the rocket must use two 1/8A impulse motors.
