I think the guy started off as legit and really loves the hobby, but got into gambling or drug addictions and ripped off everybody starting about then, ever since that time he's been wanting to get back into the hobby but he screwed over literally hundreds of people and will likely do it again as soon as he gets in a bad spot.
I don't think he actively was trying to screw people over at first, I think in his mind he believes he won't do it again, LOL So I think he's selling parts thinking oh I'm going to do it right this time, but as soon as he starts back on the drugs or the gambling or whatever it was he'll screw everybody over again.
When he was posting the complete star wars cockpits he knew for a fact, at that time, that there's no way he could pull that off so by that time he was actively trying to defraud people.
