Well I would say not necessarily a mistake but the sport 3 is defiantly not the cheapest chassis, as far as drifting. The team magic drift car is way more bang for your buck but it's belt driven so not for the beginner, then there's the Sprint 2 drift, it's cheaper, shaft driven, and more aftermarket parts, but I would take to team magic drift car over the Sprint 2.
Oh and thank you sagadsetup I do appreciate that.
