All the ideas on this car have appeared before somewhere else (ie not the DEX210).
The chassis may be a lot like Durango's, but its also like virtually every single 1/8th from a long time before the Durango.
You could get switchable mid/rear gearbox conversions for RC10's in the late '80's.
So it need not be a copy of the Durango. And even if it is, who's fault is that? If a company chooses to show off its prototypes years before it puts them into production they shouldn't be surprised if someone else gets there first!
