Ran that same system in my first scale truck and it was about as fast as a box stock 2wd slash.
Didnt have any trouble out of it but wanted to be waterproof so I switchd to Holmes Hobbies ESC's and 35t HW brushed motors and havnt looked back. Chose the waterproof option for the esc and over a year later still problem free. After winning the 2010 Indiana state TTC I cleand my rig with a blast from a garden hose.
I would not try that with a goat system.
