Depends on what you call scale. I know people that take years to build models for Scale Masters or big IMAA events. Warbirds seem to take the longest. I don't build to this standard, I have never had any reason to. I just spent about 6 months building my Sukhoi from plans. Last time I built the same plane it took 6 to 8 weeks. Most kit building takes me about 6 to 8 weeks from start to finish.
In the last 5 years I have relaxed and no longer build for other people. {If I can help it} Now days I no longer spend 10 hours in my shop and I don't bother rushing, it will get finished when it gets finished. I think I spent about 3 hours in the shop today masking and painting. I have never spent more then about 8 months on any model, kit or plans. If I was to do true scale I can understand years. A scale Extra takes less time then a scale P-47 though. Size counts too. Well, in this case anyway.
