So, the engine vs. no engine shall remain an argument for the ages. But, as I learned from a wise, and very talented, model builders years ago is, who is going to see it while it sits on a shelf collecting dust?
Also, how much more would this kit be if the extra tooling had to be made for the engine and everything that goes with it? I know, some of you would pay it, but, some of us would hesitate.
Like I said before, we as American model builders are spoiled with almost every kit having an engine, even if it is a lump of an engine. But like I also said, I would happily buy a well detailed and proportioned kit if it meant no engine. Current tooled kits have been hit and miss by U.S. kit makers, but Tamiya has been pretty consistent in quality and fidelity. And most of their kits do not have engines.
Don't believe me, then go build a Tamiya kit and then decide.
