Show Theme: “What If – Why Not?” (Also has a junior category)

This class is limited to models that are fictional, futuristic and proposed subjects in all scales. Some examples of models that would qualify under this class are:

  • Actual experimental subjects with fictitious markings (for instance, if they had gone into full service) will be placed in this class. Actual experimental subjects marked as they going to be actually used will be placed in the appropriate non-fiction category.
  • Futuristic subjects (such as Science Fiction and Fantasy models with markings and/or design changes) are covered here. (i.e., a Star Wars X-wing fighter with USAF markings)
  • A proposed subject is covered here if it never left the “design” phase. If the subject were built for testing, even though it did not enter service, it would be placed in the appropriate non-fiction category.
  • Models of actual subjects which have been modified to represent some fictional or notional vehicle or military unit (as used in movies, TV, or for actual military training) should be entered in the appropriate category for the base model which has been modified.

The burden of proof is on the modeler to show a proposed item was not built or an experimental subject was not marked as presented.

Junior – contestants 17 and under

Note: The above list is subject to change at the show depending on the number of models submitted for each category


1. This contest is sanctioned by the International Plastic Modelers Society USA, and is sponsored by the Knoxville Scale Modelers Association. Anyone may enter models in the contest; you need not belong to IPMS/USA or KSMA.


2. This contest is strictly for static scale models constructed from unassembled, unfinished commercial plastic, resin, wooden or metal kits. The following are not eligible for awards, but may be brought for display purposes only:

a. Diecast, pre-assembled/pre-finished toys or replicas.

b. Models which are not the work of a single person.

c. Models winning a 1st place in class or category at a previous KSMA contest.

d. Models winning any award at an IPMS/USA National contest.


3. FUNDAMENTAL MODELING SKILLS COUNT MOST IN JUDGING: correct parts alignment; clean assembly; seam elimination, and smooth application of finish and markings are the primary items which are evaluated. The judges will also consider technical accuracy, added detail, and general effect.


4. ALL DECISIONS OF THE JUDGES ARE FINAL. Teams of three judges will determine 1st and 2nd Place trophy awards, and Honorable Mention ribbons for each category. Automotive judging will be done using the NNL style, with each category having a 1st, 2nd and an Honorable Mention.


5. Best Aircraft, Best Armor, Best Automotive and Best Miscellaneous trophies are determined by a consensus of all the judges in each respective class. 


6. Show officials will determine the competition category of each entry at registration. Judges may at their discretion merge or subdivide categories depending on the number of entries, or move entries to other categories when appropriate. All judging decisions are final.


7. Junior categories are for modelers aged 17 or younger. 


8. Models eligible for awards must be displayed with completed entry forms. Entrants are encouraged to use the "other information’' area to document unusual color schemes or details, list appropriate handling precautions; and describe the techniques and materials used in construction. Supplemental materials may be attached.


9. A model on a base with simple 2-D terrain is considered an individual model. If there are 2 crew figures (1 can be off the vehicle) the entry is still counted as an individual model. A prime mover with trailer or towed artillery is counted as 1 vehicle.

An entry with 2 to 4 figures, or no more than 2 vehicles, low 3-D groundwork, and has no obvious theme or story, is considered a vignette.

An entry with high terrain features (trees, high walls, houses), or has an obvious theme or story, is considered a diorama.
