I have had some experience with IPMS clubs having founded a couple of chapters myself. ( Flight 19 in the Ft. Lauderdale Fl. area is still alive and well) My experience with "Local competitions, especially anything Monthly, is that there were never enough Models to break down into appropriate categories. Therefore things tended to go in LARGE groups, Prop Aircraft, Armor, Jet Aircraft, Vehicles etc. So the more familiar the subject, and most of all the flashiest WOW models, tended to win. By familiar I mean Bf109s, Mustangs, German Armor etc. No real prejudice they just judged what they understood :-)
