I am running the car with a Tamiya Transpeed 8.5t motor and Hobbywing Xerun 60A esc. I have rebuild the 3rd diff/spur once because it was too loose and slipped. I replaced the standard 3mm balls with ceramic balls and changed the pinion to a 21t pinion. Drivetrain is very beefy and holds well.
I wait for the release of GPM products for the Avante in August.
