Sounds good to me! Like the idea of a number doing the same aircraft type, or one of a type to fit a scene, for example aircraft of a particular unit. As for domination by certain people, either appoint those people as judges, so they can't take part(!!), or have a 'ranking' system, based on, eg, experience/skill level/age or whatever? Whichever way, it would be fun and encouraging to all and, as Jan says, only those who finish the model TOTALLY can be 'scored'; could make it easier to arrange/judge etc by having it strictly 'out of the box' ?
