The XXX-4 with a 9X2 handwound motor and a very good ESC.
Even RCCA rated the XXX-4 the "Fastest 4X4 in the world".
Ive broken track records with this thing. The xxx-4 is ballistic fast, its probably boaring to run stock in.
When you get your xxx-4, some recommended hopups are for MOD.
Trinity Motor mount clamp (MUST HAVE, PLASTIC BREAK EZ TO MOD)
Lundsford Titanium Turnbuckles
XXX-4 Graphite chassis
This car is the fastest offroad I have ever driven in my life, its a blast to drive.
