It mentions factory jigs... that right there tells me someone might have a bunch already invested and is going to go to town!
That said, it could also mean that they have the idea to get LOTS of $ from deposits, then go buy all the jigs...
$400,000 for a 170 or 185? really, look at the price of a new 206, and the rate folks are crashing good planes this year we are going to have a shortage of float planes soon.
There are stories published about this guy making things happen, but there are enough 'personal experiences' from some that show some of his dealings might not be on the moral high ground. I don't have the $$ for a $290,000 185 right now, much less $400,000 for a 170. I would beware, but if that was my desire I would travel down to see the jigs and processes before I walked away without meeting the man.
Remember CC used to sell 'new' cubs?
