- 37.1 Scope
-
Rocket Glider Duration Competition comprises ten events open to any single-staged model rocket that returns to the ground
in stable, gliding flight supported by aerodynamic lifting surfaces which sustain it against gravity. Models whose gliding
surfaces are made of flexible materials (e.g., plastic film or cloth) are prohibited from this event. The purpose of this
competition is to achieve the longest flight duration time.
