I don't believe that you want models with major faults in them if they can be avoided, otherwise we would all be modelling using locomotives akin to old Tri-ang locomotives of the 1960's. If you have ever seen some of the poorer attempts over the years to do an Australian locomotive you would know what I am talking about.
Some were sheer disasters would be the only way to say it. This is well before Lima even had their stuff out, If you had said back then that someone would one day do a RTR plastic Australian locomotive diesel or steam, they would have had you committed to the insane asylum very quickly.
But over the years criticism of various overseas repaints finally came to fruition when Lima made their 44 class diesel and even they had a lot wrong, but over the years these and other locomotives were upgraded, the original motors were not that good at all, the gearing made then run like a scared jack rabbit. We complained and later Lima re did the gear system in them, the Lima 38's were the same, the original had only a drive to one drive wheel, the later ones were all main wheel drive, after comments about their pulling power were aired.
If you want improvements made then you must be ready to criticise something, because if you do not, as I said the importers then think it is has been done properly and just sit back and rake in their cash, if however someone points out a bad mistake or wiring error or something then they can take steps to get it fixed if it is possible to do it.
If I was making models and someone points out a glaring error in one I know I would not throw in the towel, but get the models corrected if at all possible, if not point out the error and offer them at a reduced price or something. Just remaining mum about things only feeds the rumour mill and could damage your business.
As has been said the Chinese manufactures take all manner of short cuts to make the models you want, this is where the mistakes are probably made, but they hopefully would be picked up before the models are released.
I am not that adverse to correcting something on a model though if it is something minor, but if it requires major surgery or something to get it right then it should not really have been released to the modellers till it was fixed to the importers satisfaction! We are paying big money for current models and while I do not expect 100% accuracy of the models, we should expect pretty close to it for the money we fork out to buy them. Not all of us have a bottomless pit of money to suit our modelling needs!
I am not having a go at you or anyone else just pointing out some things that have been said to me by owners of some of the current crop of Australian manufactures, some of these comments range from extremely pleased to extremely disappointed depending on what the model is!
