to be fair it doesnt matter what tc you buy they are all on par with each other the xray is a safe bet as the kit setup works very well i personly wouldn't get the xray im very partial to the corrally phi but i did win 2 stcc and and a carpet wars with the corrally i also won a wars with an xray and a tc4 but the corrally was by far the easiest but they are not cheapest the mi4 seems to be very good and the 416 also i think the desion needs to be what colour do you want orange blue silver or purple.
