hi im looking for a kit for racing and will be buying around christmas time. I was wondering hw these ktis do racing. I heard its heavy but how does it compare to the rc9t, mugens, jammins, and losi's. Im would be coming from a thunder tiger st1 rtr is this going to be a big diff then the st1 rtr for racing. The kitsi have in mind are the rc8t, caster k8t, and hb d8t(still in making), and gs xut team pro kit. By the time i by s there gong to be a new one out of the hobao?
