what do you mean by a good intro can you rewrite it about the fair use i use the logo picture just in order to show the development link between the Grand Duc and nEUROn if you can design a DCG of the nEUROn scale model do it i used this one because as a correction since the previous pic was an  outdated prototype namely the Grand Duc i have updated this article and i am responsible for the LOGIDUC but im currently too busy to spend time on wiki so good luck
