I would recommend a sakura d4. You can find them in many shops online. A good motor would be something between 10.5 and 13.5t for rwd and for cs you i seen them run down to 7.5 but a good point is between 10.5 and 8.5. Here is a basic combo for rwd.(link) and this one for cs.

You will also need a lipo but that depends on how much run time you want i would recommend the turnigy hard pack lipo (link). And a radio system. Here is a basic one (hh) last thing you need is a servo and a good one is Savox SC-1258TG (link) another thing need if you go the rwd route is a gyro

Or you can always get a mst rtr (link) if you dont want to build your own and want something already build.
