I chose to mount it that way in order to use available dogbones from my parts bin. I used UE's dogbone for the thunder with the mono in the rear and UE's 70mm titanium dogbone in the front. There is still enough space to drill new mounting holes if I decide to use different size dogbones but for now, this setup will do.
Center diff is an Ofna with 44T spur and a 15T RCM pinion. I'll be replacing the diff pinion with an Ofna 10T to lower my top speed. Right now, the diffs are buggy diffs(43/13). I'll be running this on 5S :.
Here are pics of the finished assembly:
I used a 7/32 mill bit to make the recessed holes.
I'll be making a new chassis plate out of 7075T6 aluminum. It will be longer by about 2 inches compared to the stock plate. Here's the template I'll be using:
Castle Neu 1520 on 6S LiPo Powered Gmaxx (Nitro Killer)
Predator with OS .21TM
Supermaxx with Mach .26
Revo with OS .18TZ
Kyosho ST-RR Conversion
Ofna CR with Tekin ESC/Motor (2)
