The ER-12 is based off the DEX210 and that has been said from the very beginning. That has never been denied, but it is not a clone or exact copy.
I can't speak for the Intech engineers, but I would guess they looked at all the buggies out there, then choose the one that had the best features, and used that platform to design their buggy. They basically just tried to improve on a proven platform. If it was an all new design from Taiwan, no one would buy it unless they spent tons of money hiring top drivers to fly around the world and win big races. But since it looks like a buggy people know works, then they are more likely to give it a try.
IMO, the ER-12 is way better then the DEX210. It comes with way more upgraded parts and it does not fall apart and break just going around the track. They both handle well, so the better one is the one that does not DNF every race. Only time will tell.
