A Engine Boost Glider Duration

36.1 Boost Glider Duration Competition comprises nine events open to any model rocket, one portion of which returns to the ground in stable, gliding flight supported by aerodynamic lifting surfaces which sustain that portion against gravity. If the entry is staged, the gliding portion must be part of the uppermost stage, and must not be deployed until that stage has burned out. The entry may separate into multiple pieces; only the gliding portion is timed. 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.

36.2 An entry that descends with parachute and/or streamer recovery device(s) permanently attached to the gliding portion of the model shall be disqualified. However, other portions of an entry may deploy parachutes and/or streamers for recovery purposes.

(If the glider entry accidently rips the motor pod's recovery streamer and the streamer attaches itself to the glider, the entry may be qualified depending on the RSO ruling that the entry still glided and was not disqualified for other reasons)

36.3 This competition is divided into classes based on the permissible total impulse of the motor(s). The following classes of Boost Glider Duration Competition are established:
