RE: Scale Question
Its true, if you read the rules for Top Gun. They go off the documentation you provide. If you provide views of both sides with markings,then it should match your plane, whatever is on the your documentation. The judges do not know all the planes scale details. They cannot go from what they think its suppose to look like, they may never have seen that airframe entered. Therefore they would need your documentation.
now if you want to know about a particular plane just have it right, then ask here on RCU, someone will have a pic of what you need.
