My apologies if anyone mentioned it and I missed it but Exotek has a couple of new things out for the 210. The new rear motor HRC bulkhead conversion is the same mod that Jorn Neumann used at the 2014 Euro Championships. It looks like a nicely machined piece.

They've also got a new V2 style rear tower that is 5mm thick.
