I believe that there was a person asking for help and advice on this forum a few years back who intended to build a static Hetzer from resin and white metal, he was not made welcome with some negative remarks, some wanted a full RC compatible model with alloy tracks and sprockets along with DMD and battle system for less than 100€ built, these same individuals couldn’t understand the investment involved in making a static kit let alone a full RC kit.

As for anyone making a CAD drawing to try and sell a model supposedly as some sort of sham then they do not understand CAD drawing yes anyone can use it these days but to build a CAD model like this person has done will take at least 6 months of hard work and a heck of a lot of research, now if anyone can build a CAD model to this level of detail in 6 months or less then you are in the wrong job and should be highly paid, however I do agree that they should have built a prototype and pictures of this should be shown, as for resin tracks well the chap has only ever claimed it to be static and that by drilling and pinning the tracks they will hang in an appropriate manner aching to the real thing nothing more.
