You have to put as much in any truck, kits have no engine and rtr's don't have .12's anymore and other than the tires, radio and engine, my Jato is factory right down to the servo's, even if i used a few optional parts.
crazyjr- what do you have to do to get a .12 with a sg crank in a Jato? I'm having prblems with the flywheel being to thin? What flywheel/clutch bell & clutch nut did you use.. Thanks firstname.lastname@example.org
