where can you get the motors for the cars? is there a certains series you need or what? what all do i need to do it? also can you do the big dub city trucks and cars? do you know if they got bags for them or just Juice
since you are new to this, your best bet would be to buy a Hoppin Hydros kit. it's a chassis with the motors already in it and the switches are prewired. all you gotta do is run the strings and install the "U-bars" or "T-sliders" depending on which you wanna run. (those are the "suspension" pretty much) then install a set of axles, wheels & tires and maybe do a little trimming on the chassis and body to get it to fit.
that is what i did for my first one just to get the feel of things.
