That's a good looking truck right there!
I love the Medusa Motors. A 36-70-2000kv is powering my E Revo now. The 70mm is pretty much an ideal size for the E maxx and E Revo IMO.
If you gear it up, it will really toss the truck around, or if you gear it down, it'll run all down long and you'll never have to worry about temps.
Liquid Electric Tape? Got some more info on that? A closeup of the ESC would be nice. Did it turn out ok?
While running my E Revo today, I ran off into a mudhole. It didn't hurt anything, but it always make me think the worst.
It's hard to wait until everything is perfect outside when you're wanting to run your truck.
