Between my career and demands of my time as a husband, father, and homeowner......It's hard for me to sit down uninterupted for a couple hours and work on a model. I usually piddle paddle at it for months. That B-24 I built probably took close to two months of just working on it here and there. It's what I like about it.......I can drag it out as long as I like...or not. Model complexity and quality play a significant role in determining the time spent as well.

It's all personal choice....if you choose to "bang it out"....you could probably put a handfull of model planes on the shelf pretty quickly.
