You make this sound like a bad thing. Just remember, when you're doing a scale model, you have to do your research. I'm presently building several scale unlimited hydroplanes and, even though a couple are basically the same boat, the differences in the paint schemes alone is almost enough to drive you to drink. The picture on the left is the boat as it appeared in it's second year of racing. The shot in the center is the same boat racing in 1978 while the one on the right is how it looked, less wing and engine, after it's last race in 1988. I'm building the left and center versions, would you like to help?
