- 33.1 Scope
- Super-Roc Duration Competition comprises nine events open to single-staged model rockets whose body length is
no less than the minimum allowed for the classes of the event. The purpose of this competition is to achieve the
greatest duration possible with the longest rocket possible without impairing the structural integrity of the rocket.
-
- 33.2 Structural Failure
- An entry that comes apart, bends so as to crimp the body, or has a similar structural failure prior to ejection shall
be disqualified.
-
- 33.3 Construction
- Entries with bodies or significant structural parts made from hard or potentially unsafe material (e.g., hardwood
doweling or fiberglass shaft) shall not be allowed, under the provisions of Rule 1.1.
-
- 33.4 Scoring
- Super-Roc Duration Competition shall be scored as follows: the length in centimeters of the model, as measured from
the tip of the nose cone to the end of the motor nozzle, up to the maximum length for that category, shall be awarded as
static points. No additional points are awarded for any length beyond the maximum. The achieved duration of the model in
seconds shall be awarded as flight points. The static points and flight points thus obtained shall be multiplied to
determine the total points for each flight. The contestant achieving the highest score is the winner.
-
- 33.5 Classes
