This is going to sound like a weird question, but why do you build the models that you do. For me, I try to build the models that I put gas on, which is why a lot of my on deck's are heavies as I was stationed at a heavy base and that's what we normally put gas on, outside of the transient aircraft that came on base. Is it looks, difficulty or what not.
Edit:If any of y'all come across a KC-10 kit (think Revell made it) let me know....
