A little flex isn't necessarily a bad thing, either. Flex = traction as long as it doesn't flex enough to bind something. The 4mm chassis will likely last longer, as it is thicker and slightly softer(less prone to stress cracks). The extra weight of the thicker plate will lower the overall Cg slightly.

Get the IRC E-Chassis. Fit & finish is perfect and the absence of nitro holes helps keeping the dirt out.

You can use a E-Revo or similar radio box and mount behind the front shock tower.
