Its amazing what you can find out by contacting the company concerned...

As stated, there is no solid-plan for a G4 chassis yet, just lots of possible ideas; dont expect to see anything before next summer would be my educated guess.

The G3r is fine, and if you ask Mike nicely he will make a you a center diff/drive unit like a few people have round here for the Gmaxx chassis- nice low CoG and clean looks to boot.

Why not design something of your own based around the 3905 spec tranny, and have Mike or Metal man machine it up for you; just use a stock revo chassis for reference (hole spacing and general layout), and work from there- several guys have made their own center drive units with little more than basic tools.
