Which are the Main USMRSC Rules for This Event?
Does TCC Have Supporting Documents?
TCC has created a CM Judging Form and instructions. Since CM is based on Sport Scale, TCC includes documentation for judging and winning Sport Scale by Peter Alway and John Pursley.
What is the Goal?
* You want produce a flying replica of a model rocket kit that was available (for sale) prior to 1990 (1989 or earlier. USMRSC P57.1
Does it Qualify for CSC?
* The model you choose to replicate: USMRSC P57.1
1. Must represent a version of a flying model rocket kit that was offered for sale by a model rocket kit manufacturer in the year 1989 and earlier.
Are There Any Special Considerations?
* Substantiation data is different from that required by Sport Scale. USMRSC P57.3 You must substantiate (prove) that your entry was available for sale in kit form in prior to 1990 (in 1989 or earlier) and that you have reproduced, to scale, the shape, color and paint pattern depicted by the manufacturer. USMRSC P57.1, USMRSC P57.3
Your substantiation data can come from one or more of these sources:
Catalog: TCC suggests an original catalog or a reproduction from a verifiable source such as Ninfinger (http://www.ninfinger.org/rockets/rockets.html).
Package insert: TCC suggests original only, not a reproduction or reissue.
Original kit instruction: TCC suggests original or reproduction from a verifiable source such as Jim Z (http://www.spacemodeling.org/JimZ/index.htm).
2. Without this data, contest officials will not accept your entry.
* No one can catch the model. If anybody catches the model as it descends instead of letting it hit the ground, the judges may award maximum damage points as a penalty. USMRSC 16.7
Do I Have to Return My Entry?
* The Contest Director can require that you return your entry. USMRSC 9.10
How Many Flights Can I Make?
How is the Competition Scored?
* In static scoring, the judges award points for craftsmanship and appearance, taking into consideration the difficulty of converting the model to fly.
* In flight scoring, the judges award points for conducting a ‘mission’, for achieving a safe and stable flight, and deduct points for damage (damage points) the model receives on landing. If you cannot return your model to the judges after its flight, the judge will award maximum damage points which will be subtracted from your final score.
What Will Disqualify My Entry?
* Your entry will be disqualified if it fails to make a safe and stable flight. USMRSC P57.5
How About Some Suggestions for New Competitors?
* Chose a kit that you can build. Don’t try to learn a new skill for this event. If you haven’t built a clustered or staged model before, don’t do it now.
What Else & What Next?
Classic Model is making its first appearance at NARAM this year (2011-2012, NARAM 54). Check with your section’s Contest Director to see if your section will be hosting a CM event this year. Contact your Regional Contest Board Chairman for more information on competing in Classic Model.
TCC’s Classic Model Judging Form Pack, TCC CM Judging Form Pack, comprises a form for recording the judges’ point awards along with discussions by Peter Alway and John Pursley on judging, scoring and winning Sport Scale (SPSC). Since CM is based on SPSC, these discussions will help you maximize your points.
