muggy build-up from scratch?

The motor mount is home made. It isn't anything special; it's the same principal used my many. It simply bolts to the center diff mount and has slots cut into it to accommodate the motor.

The gear pitch is module 1 (mod1).

I did make aluminum rock guards for it last night. I used T6-6061 1" wide and 1/8" thick aluminum bar. Now there is less chance of something flying up under the body and the chassis in much more rigid, with only the slightest flex. I'm going to order some carbon fiber and remake the parts to cut down on weight.

With the battery, the truck weighs over 12lbs, although you wouldn't know it if you see it run.
