Finnster, I like that Savage layout a lot... Should allow both batteries to sit inside the FLM extended low CG TVPs as well. Only thing is, I wouldn't incorporate the servo mounts into the upper deck as I am using the FLM servo mounts which IMO would be a simpler option.

Have you considered designing a CD mount similar to what I have on my Savage? This is just about the strongest way to do it (from what I have found), because it incorporates the motor and center diff into the chassis, which also strengthens the chassis. The skidplate method is definitely easier, but the attachment points for the skidplate are few and far between, and you will lose some chassis strength as well.

Last point, if you go with a Slipperential, I can pretty much guarantee you won't have any issues with the Flux diffs. This means you could go back to the original diff ratio and use the 46t gear.
