only some days not around here...
Well the maxx is/was mine
It was one of my first works so quite ok but not perfekt.
I hadn't got the enough time for the hobby in the past but i started desgining a new chassis. Centerdiff+Slipper (like Slipperential), of course lipos and i wasn't sure about it but i thought about using an outrunner bl... i would have also used an mechanical brake.
I would build the chassis like " lego-principle" to make working on the truck more comftable. on the basis-chassis all over units (batterymount, centerdiff+Motor...) build up..
The CF inserts aren't really neccessary more for show... But i would "play" with the different materials, a truck complete out of alu isn't the best way...
Just for notice if you are looking for an ue razorback here:
