SCOTTISH NATIONAL SCALE MODEL SHOW COMPETITION DEFINITIONS AND RULES
​
Updated 01/03/2025
​​
All models will conform to the following definitions and rules.
​
DEFINITIONS
​
1. Figures - In all classes except dioramas, each entry may be displayed with EITHER the crew members and/or passengers (who must be in or on the aircraft/vehicle etc) OR with one figure on the base to indicate scale … NOT both. Figures placed on/in the aircraft/vehicle and on the base shall mean that the entry is classed as a diorama. Figures may be from any source.
​
​2. Bases and Cases - Bases will be allowed in all categories and will not be considered in the judging except dioramas. The base will not be larger than 1.5 times the model size. Modellers can enter one model with a base no larger than A2 in size (42x60cm), or two models with bases no larger than A3 in size (30x42cm). Anything larger than A2 must be pre-registered with the Competition Secretary and approved well ahead of the date of the Competition. A base may simulate the natural surface on which the prototype may be found to show the subject in context for example uneven ground to show vehicle suspension deflected, runway markings etc. A small amount of natural surroundings is also allowed but this may not deflect from being able to see all sides of the model. Aircraft requiring beaching gear or trolleys may be so equipped. Ships may be displayed on water, but dry-docks are not allowed. Glass cases are permissible for public viewing periods but, with the exception of the ship classes, must be removed by the entrant for judging and photography purposes. Failure to comply may mean entries are not judged and/or awards withdrawn.
3. Dioramas - A diorama shall be defined as one or more items (not necessarily from the same class) on a scenic base, with or without figures, conveying a specific theme or real life situation. Modellers can enter one single diorama with a base no larger than A2 in size (42x60cm), or two dioramas with bases no larger than A3 in size (30x42cm). Diorama base sizes exceeding A2 must be pre-registered and approved well ahead of the show by the Competition Secretary. If an entry contains major elements from more than one class (except for vehicles shown with their normal load) it will be a diorama.
