Need help with my G3-build

[JoFreak]

I tried a vid on page 6, didn't seem like too many of you were interested

Apart from that, the build is doing nicely.
I'm makin major changes at the moment, ditched the schulze 18.97kw and the bigmaxximum for a castle 1518 1Y and a mamba monster.
Also swapped the 2x2S hardcases against 2x3S turnigys.
Upgraded the servo and the steering, but I'm pretty shure I mentioned all of that somewhere in this thread...

As of this moment I wait for mike to answer my e-mail (disturbingly for sever about the custom battery trays I designed with CAD. Those should be a perfect fit to the G3 lower chassis plate and prevent the LiPos from flying around after crashes.
Up till now nothing happened, but up till now those were hardcase LiPos flying arround...

Furthermore I have to see when I find the time to bring the motor/CD mount to a friend of mine, to modify it so the slipperential (46T mod1) will fit into the mount and all together into the chassis.
And more importantly, modify it in a way that the motor will not collide with the heads of the screws that hold the top plate of the mount so I can use pinions in a size that won't make my truck hit warp 10 and travel through time

Could need some suggestions on how to support the rear end of the motor against the chassis though.
