Thank you for your comments and thoughts on the issues I have been discussing. I can only direct my views from the He 219 build, as I have not built any other ZM's kits but do have their Skyraider in my stash. Of course it is unfair to compare most manufactures or any to Tamiya, as Tamiya has been learning and still improving their craft for 50 plus years or more. What it cost a company to produce quality molds is none of my concern nor business, as I haven't a clue as to what their costs actually are. If it takes mold engineers to do it right, then that's what it takes and the list goes on. My observations and experience building the kit so far, based on what the the kit costs, as to the quality of molding, as well as the instructions are how I feel and nothing more. If there is a long term learning curve in producing upper level and expensive kits, then maybe companies should learn to walk before they try to run. Possibly they were over ambitious in what they were able to produce without first perfecting the art. Possibly, less complicated kits at the start would have served them better. All of this has nothing to do with the usefulness of the instructions. The old motto of you get what you pay for, doesn't seem to apply here.
I'm well into a $274 kit with the four "ZM Upgrade Sets" I've purchased and even at the kit cost of $174, that an expensive kit.
In all my build threads I try to show and discuss what I am doing and my personal thoughts regarding the kit. Most of my builds are OOB, so I'm not cutting up or changing a kit but building mostly what is in the box.
If this was someone else build thread and I was looking to buy the kit, would I let it sway my decision one way or another .. maybe. It's just my personal observations and thoughts
